Hair Loss and Its Causes
What is the normal cycle of hair growth and loss?
The normal cycle of hair growth lasts for 2 to 6 years. Each hair grows approximately 1 centimeter (less than half an inch) per month during this phase. About 90 percent of the hair on your scalp is growing at any one time. About 10 percent of the hair on your scalp, at any one time, is in a resting phase. After 2 to 3 months, the resting hair falls out and new hair starts to grow in its place.
It is normal to shed some hair each day as part of this cycle. However, some people may experience excessive (more than normal) hair loss. Hair loss of this type can affect men, women and children.

What causes excessive hair loss?
A number of things can cause excessive hair loss. For example, about 3 or 4 months after an illness or a major surgery, you may suddenly lose a large amount of hair. This hair loss is related to the stress of the illness and is temporary.
Hormonal problems may cause hair loss. If your thyroid gland is overactive or underactive, your hair may fall out. This hair loss usually can be helped by treatment thyroid disease. Hair loss may occur if male or female hormones, known as androgens and estrogens, are out of balance. Correcting the hormone imbalance may stop your hair loss.
Many women notice hair loss about 3 months after they've had a baby. This loss is also related to hormones. During pregnancy, high levels of certain hormones cause the body to keep hair that would normally fall out. When the hormones return to pre-pregnancy levels, that hair falls out and the normal cycle of growth and loss starts again.
Some medicines can cause hair loss. This type of hair loss improves when you stop taking the medicine. Medicines that can cause hair loss include blood thinners (also called anticoagulants), medicines used for gout, medicines used in chemotherapy to treat cancer, vitamin A (if too much is taken), birth control pills and antidepressants.
Certain infections can cause hair loss. Fungal infections of the scalp can cause hair loss in children. The infection is easily treated with antifungal medicines.
Finally, hair loss may occur as part of an underlying disease, such as lupus or diabetes. Since hair loss may be an early sign of a disease, it is important to find the cause so that it can be treated.

Can improper care of my hair cause hair loss?
Yes. If you wear pigtails or cornrows or use tight hair rollers, the pull on your hair can cause a type of hair loss called traction alopecia (say: al-oh-pee-sha). If the pulling is stopped before scarring of the scalp develops, your hair will grow back normally. However, scarring can cause permanent hair loss. Hot oil hair treatments or chemicals used in permanents (also called "perms") may cause inflammation (swelling) of the hair follicle, which can result in scarring and hair loss.

What is common baldness?
The term "common baldness" usually means male-pattern baldness, or permanent-pattern baldness. Male-pattern baldness is the most common cause of hair loss in men. Men who have this type of hair loss usually have inherited the trait. Men who start losing their hair at an early age tend to develop more extensive baldness. In male-pattern baldness, hair loss typically results in a receding hair line and baldness on the top of the head.
Women may develop female-pattern baldness. In this form of hair loss, the hair can become thin over the entire scalp.

Can my doctor do something to stop hair loss?
Perhaps. Your doctor will probably ask you some questions about your diet, any medicines you're taking, whether you've had a recent illness and how you take care of your hair. If you're a woman, your doctor may ask questions about your menstrual cycle, pregnancies and menopause. Your doctor may want to do a physical exam to look for other causes of hair loss. Finally, blood tests or a biopsy (taking a small sample of cells to examine under a microscope) of your scalp may be needed.
Return to top
Is there any treatment for hair loss?
Depending on your type of hair loss, treatments are available. If a medicine is causing your hair loss, your doctor may be able to prescribe a different medicine. Recognizing and treating an infection may help stop the hair loss. Correcting a hormone imbalance may prevent further hair loss.
Medicines may also help slow or prevent the development of common baldness. One medicine, minoxidil (brand name: Rogaine), is available without a prescription. It is applied to the scalp. Both men and women can use it. Another medicine, finasteride (brand name: Propecia) is available with a prescription. It comes in pills and is only for men. It may take up to 6 months before you can tell if one of these medicines is working.
If adequate treatment is not available for your type of hair loss, you may consider trying different hairstyles or wigs, hairpieces, hair weaves or artificial hair replacement.
Male menopause: Myth or reality?

Male menopause: Myth or reality?
Sometimes called male menopause, aging-related hormone changes are very different in men than in women. Learn about symptoms and treatment.
By Mayo Clinic staff Less interested in sex lately? Tired? Grumpier than usual? Is this a midlife crisis brewing? Or are you feeling the normal hormone changes associated with aging? Hormone changes are a natural part of aging for men. But male menopause is not an accurate description. Unlike the more dramatic hormone plunge that occurs in women during menopause, hormone changes in men occur gradually, over a period of many years, the effects of which are often subtle and not noticed until much later in life. Some men are never affected by lower hormone levels at all — while some have physical and psychological symptoms that can include changes in sexual function, energy levels or mood. While the term "male menopause" is sometimes used to describe decreasing testosterone levels related to aging, Todd Nippoldt, M.D., an endocrinologist at Mayo Clinic, Rochester, Minn., prefers the term "andropause." "There needs to be a distinction because we're dealing with two different situations," he says. "In women, ovulation ceases and female hormone production plummets over a relatively short time frame. In men, there's a gradual decline in the production of male hormones." Age-related decline in testosterone levels are also called testosterone deficiency, androgen decline in the aging male (ADAM) or late onset hypogonadism (LOH).Male hormones over time
In general, older men have lower testosterone levels than do younger men. After age 40, testosterone levels in the blood begin to decline gradually — at a rate of about 1 percent a year. While there's a steep drop between the ages of 45 and 50, reduction in testosterone levels are rarely significant enough to be noticeable in men younger than 60. By the time men reach their 80s, about half have low testosterone. But testosterone levels vary greatly among men — and some men maintain normal testosterone levels into old age. Other men who have low testosterone levels don't have bothersome signs or symptoms.What are the symptoms of andropause?
Lower than normal testosterone levels do not cause symptoms in all men — and signs and symptoms of low testosterone vary from person to person. Some of these signs and symptoms are a normal part of aging. The only sure way to know whether you have low testosterone levels is through blood tests. Signs and symptoms of low testosterone can include:- Reduced sexual desire
- Infertility
- A decrease in spontaneous erections (such as during sleep)
- Swollen or tender breasts (gynecomastia)
- Loss of body and pubic hair
- Small or shrinking testes
- Height loss and thinning bones
- Reduced muscle bulk and strength
- Hot flushes and sweats
- Decreased energy, motivation and self-confidence
- Feeling sad or depressed
- Poor concentration and memory
- Sleep apnea or other sleep problems
- A low red blood cell count (mild anemia)
- Increased body fat
- Diminished physical or work performance
Testosterone replacement therapy
Treatment of low testosterone due to aging with testosterone replacement therapy (TRT) is controversial. The benefits of TRT are not clear, and it may increase the risk of prostate cancer. While certain men who have symptoms related to abnormally low testosterone may benefit from testosterone replacement therapy, it isn't appropriate treatment for most aging men. While it has been shown to help some men with low testosterone, TRT has risks, especially for men with certain health conditions such as prostate cancer and heart disease — and it may not improve your symptoms. More studies need to be done to determine the effectiveness and safety of TRT in aging men, and who can benefit most from this type of treatment. As it turned out with hormone replacement for women, TRT may have possible long-term risks that are not yet known.Herbal supplements: Do they work?
Although many herbal supplements are widely marketed with the claim that they can relieve symptoms, none has been proved safe and effective for aging-related low testosterone. One of the most common supplements marketed to treat this condition, DHEA, may increase the risk of prostate cancer. More studies are needed to evaluate possible health benefits — and dangers — of taking DHEA or other supplements. Talk with your doctor before taking any herbal supplements, as some can cause side effects or cause problems with medications.Is it low testosterone — or is it something else?
Symptoms caused by testosterone deficiency are similar to symptoms caused by other things. Signs and symptoms can include:- A number of other health problems such as liver disease, kidney failure, or an overactive or underactive thyroid
- Side effects of medications
- Lifestyle choices such as excessive alcohol use or use of illegal drugs
- Psychological conditions, such as depression or emotional distress related to life changes that come with middle age (the so-called midlife crisis)
Steps that may help
While there's no way to avoid lower testosterone levels caused by aging, there are a few things you can do to help prevent or improve symptoms caused by the condition:- Eat right and stay active. Regular exercise and a healthy diet can help you maintain your strength, energy and lean muscle mass. It can also improve your mood and help you stay sharp as you get older.
- Talk to your doctor about sexual problems. Erectile dysfunction and other sexual issues are common as men get older. Your doctor can help you find the best way to cope. Medical treatment, lifestyle changes or changes to the dose or types of medications you take may help.
- Seek help if you feel down. Many older men suffer from depression. It often goes undiagnosed — but treatment can make a big difference in how you feel. Depression in men doesn't always mean having the blues. You may have depression if you feel irritable, isolated and withdrawn. Other signs of depression common in men include working all the time, drinking too much alcohol, using street drugs or seeking thrills from risky activities.
Belly fat in men: Why weight loss matters

Belly fat in men: Why weight loss matters
Belly fat is unhealthy. Find out what causes belly fat, the health risks it poses for men and what you can do to lose the extra pounds.
By Mayo Clinic staff If you're carrying a few extra pounds, you're not alone. But this is one case where following the crowd isn't a good idea. Carrying extra weight — especially belly fat — can be risky. Michael Jensen, M.D., an endocrinology specialist at Mayo Clinic, Rochester, Minn., answers common questions about belly fat in men.Why is belly fat a concern for men?
People who gain belly fat are at greater risk of serious health problems than are people who accumulate fat in other areas — and men are more likely than women to gain weight around the waist. Having a large amount of belly fat increases your risk of:- Heart disease
- Stroke
- Some types of cancer
- Type 2 diabetes
- Insulin resistance
- High triglycerides
- Low levels of high-density lipoprotein (HDL), or "good," cholesterol
- Metabolic syndrome
- Sleep apnea
How can you tell if you have too much belly fat?
Your waist size is a good indicator of whether you have too much belly fat. Although measurements that compare your hip and waist circumference (waist-to-hip ratio) or compare your height and weight (body mass index) are more precise, your waist size alone can give you a good estimate. For most men, the risk factors for heart disease and other diseases increase with a waist size greater than 40 inches (102 centimeters). To measure your waist:- Place a tape measure around your bare abdomen just above your hipbone.
- Pull the tape measure until it fits snugly around you but doesn't push into your skin.
- Make sure the tape measure is level all the way around.
- Relax, exhale and measure your waist — no sucking in your belly!
Does age play a role in gaining belly fat?
As you age, you lose muscle — especially if you're not physically active. Muscle loss can slow the rate at which your body burns calories. In turn, if you don't limit your calories or increase your physical activity, you may gain weight.Is belly fat inherited?
Your genes can affect your chances of being overweight or obese, as well as where you carry extra fat on your body. For most men, however, the problem likely has more to do with lifestyle than inherited traits.Can you really get a beer belly from drinking?
Drinking excess alcohol can cause you to gain belly fat — the "beer belly." However, beer alone isn't to blame. Drinking too much alcohol of any kind can increase belly fat, although some research suggests wine may be an exception. If you drink alcohol, do so in moderation. Limiting yourself to two drinks a day will reduce the amount of calories you consume and help you avoid gaining belly fat. It's also better for your overall health.How do you get rid of belly fat?
Whether you're trying to lose belly fat or trim fat from another part of your body, weight-loss basics remain the same:- Reduce calories. Reduce your portion sizes. Replace your usual fare with healthy foods that contain fewer calories.
- Increase physical activity. The Department of Health and Human Services recommends adults get two hours and 30 minutes a week of moderate aerobic activity or one hour and 15 minutes of vigorous aerobic activity, in addition to strength training. You may need to do more to lose weight and keep it off.
Can you reduce belly fat with sit-ups?
Sit-ups help make your abdominal muscles stronger, but spot exercises alone won't specifically reduce belly fat. The best way to shrink your waist size is to lower your total body fat through healthy eating and exercise.The bottom line
If you have a spare tire, don't despair. You can lose belly fat — it just takes patience and effort. In fact, shedding even a few extra pounds can help you feel better and lower your risk of health problems.Cancer de la Prostata
Friday, March 20, 2009 at 1:27PM
El cáncer de la próstata es una enfermedad en la cual se forman células malignas (cancerosas) en los tejidos de la próstata.
La próstata es una glándula que pertenece al sistema reproductor masculino localizada justo debajo de la vejiga (el órgano que recoge y desecha la orina) y delante del recto (la parte inferior del intestino). Su tamaño es como el de una nuez y rodea una parte de la uretra (el tubo que conduce la orina al exterior desde la vejiga). La glándula prostática produce un fluido forma parte del semen.
El cáncer de la próstata se encuentra principalmente en varones de edad avanzada. A medida que los hombres envejecen, la próstata puede agrandarse y bloquear la uretra o la vejiga. Esto puede ocasionar dificultad para orinar o interferir con la función sexual. El problema se conoce con el nombre de hiperplasia prostática benigna y si bien no se trata de un cáncer, es posible que se necesite la cirugía para corregirlo. Los síntomas de la hiperplasia prostática benigna o de otros problemas que afectan la glándula pueden ser similares a los síntomas del cáncer de la próstata.
Algunos de los posibles signos del cáncer de la próstata comprenden una disminución del calibre del chorro urinario o aumento de la frecuencia de la micción (expulsión de la orina).
Estos y otros síntomas pueden ser ocasionados por el cáncer de la próstata. Existe la posibilidad de que otras enfermedades ocasionen los mismos síntomas. Se debe consultar con el médico en caso de que se presente cualquiera de los siguientes problemas:

Próstata normal e hiperplasia prostática benigna (HPB). Una próstata normal no obstruye el flujo de la orina desde la vejiga. El agrandamiento de la próstata ejerce presión sobre la vejiga y la uretra, y obstruye el flujo de la orina. |
- Disminución del calibre o interrupción del chorro urinario.
- Aumento de la frecuencia de la micción (especialmente por la noche).
- Dificultad para orinar.
- Dolor o ardor durante la micción (expulsión de la orina).
- Presencia de sangre en la orina o en el semen.
- Dolor en la espalda, las caderas o la pelvis que no desaparece.
- Dolor con la eyaculación.
- Examen digital del recto (EDR): consiste en un examen del recto mediante el cual. El médico o la enfermera inserta un dedo dentro de un guante lubricado en el recto y palpa la próstata a través de la pared rectal en busca de nódulos o áreas anormales.
Ampliar Examen rectal digital (ERD). El médico inserta un dedo dentro de un guante lubricado en el recto y palpa la próstata para determinar si existe alguna anomalía. - Antígeno prostático específico (APE): prueba de laboratorio que mide las concentraciones del APE en la sangre. El APE es una sustancia producida mayormente por la próstata que se puede encontrar en mayor cantidad en la sangre de los hombres que tienen cáncer de la próstata. La concentración de APE también puede ser elevada en los hombres que sufren una infección o una inflamación de la próstata, o que tienen una hiperplasia prostática benigna (HPB; aumento de tamaño de la próstata de origen no canceroso).
- Ecografía transrectal: procedimiento por el cual se inserta en el recto una sonda que tiene aproximadamente el tamaño de un dedo para examinar la próstata. La sonda se utiliza para hacer rebotar ondas de sonido de alta energía contra los tejidos internos de la próstata (ecografía) y crear ecos. Los ecos forman una imagen de los tejidos corporales denominada ecograma. La ecografía transrectal también se puede usar durante una biopsia.

El patólogo examina la muestra en busca de células cancerosas y determina la puntuación de Gleason. La puntuación de Gleason varía de 2 hasta 10 y describe la posibilidad de que el tumor se disemine. Cuanto más baja la puntuación, menor la probabilidad de diseminación del tumor. Existen dos tipos de procedimientos de biopsia que se emplean para diagnosticar el cáncer de la próstata.
- Biopsia transrectal: extracción de tejido de la próstata mediante la inserción de una aguja fina a través del recto hasta la próstata. Este procedimiento se suele practicar con ecografía transrectal para ayudar a guiar la aguja. Un patólogo examina el tejido al microscopio en busca de células cancerosas.

ACTIVITIES FOR MEN'S GROUPS
How to give life to your men's ministry
Ideas for Success
1. Pray for guidance, and that the Lord will help you select a few good men to plan and lead.
- a. Brainstorming is offering all kinds of suggestions for the men's group. (Be sure you have someone to write the ideas down on a chalkboard or white marker board--and it should be someone who can write fast!). No one is to react to any idea negatively. In other words, if someone says , "Wouldn't it be a good idea to have a skydiver drop in with a special telegram from the governor?," you don't laugh or say, "that's silly!" Rather, you just keep the ideas flowing.
- The faster the better, and what happens is fascinating: The imaginative mind seems to come unlocked and a stream of ideas flows out. Finally, when you have exhausted the ideas, you then review and rank them. Select your favorites and then develop the logistics of how the idea can work best for your situation. Pencil in events on specific dates as a "tentative" or "first draft" concept.
- As you finesse your ideas you will have a whole list of possibilities and the well will never run dry for inspiring things to do.
- b. If you come to a sticky point or have difficulty, simply pause and have prayer. Pray specifically that the Lord will give you ideas which will bless your men and lead them to a realization of their need to grow as Men of God.
- "One night's freedom from dishwashing"
- "One pizza for the evening of your choice"
- "One good, long walk together"
- "One new outfit of your choice"
- "One new nightgown of my choice"
- "Men, you and I need to own for ourselves that same clarity of vision that so marked the life of Christ. We need to give ourselves up for our brides and the Bride as He did. So that the family might live well...... There's a world out there that needs some Tender Warriors. It's every man's purpose... every woman's dream... and every child's hope. It's the definition of a man. I want to head up that road. My prayers are with the men of this conference as we plan in our respective churches. I believe God has some wonderful things in store for us and our families that will be the result."
