Swollen Feet and Ankles

Your leg muscles function like a second heart to pump fluid from your legs to your heart. When your leg muscles relax, the veins near them fill up with blood. When your leg muscles contract, they compress the veins and squeeze blood up toward your heart.

Exercise lowers homocysteine

A regular exercise program helps to lower high blood levels of homocysteine, according to a study from multiple medical centers (European Journal of Applied Physiology, November 2006). High blood levels of homocysteine increase your risk for heart attacks, but at this time, nobody knows why. More than 200 papers show high blood levels of...

Agent Orange Does Not Cause Diabetes

In April 2000, a study from the Air Force was widely reported in newspapers to have shown that agent orange causes diabetes. Only Gina Kolata of the New York Times wasn't fooled (NYT, April 20, 2000).

Impotence in Men with Diabetes

A study from Italy shows that more than 56 percent of diabetic men suffer from impotence, and almost all complain bitterly that it has destroyed something that is very important to them. The study also shows that most men who are impotent from diabetes are depressed. Impotence caused by diabetes can be prevented in almost all men whose bodies can still make insulin.

Who is Pre-Diabetic?

You can tell if you are at high risk for diabetes if you store fat primarily in your belly. Pinch your belly; if you can pinch an more than an inch of fat under the skin there, you are at increased risk and should get a blood test called HBA1C. Having high blood levels of triglycerides and low levels of the good HDL cholesterol that helps prevent heart attacks also increases your risk for diabetes.

PSA Test for Prostate Cancer

Many doctors recommend that every man over 40 get a blood test called Prostate Specific Antigen to check for prostate cancer. Prostate Specific Antigen is made by prostate cells and is released into the bloodstream. Large prostates have more PSA, so a rise in PSA means that the gland is enlarging rapidly, which can be a sign of cancer or that the prostate is irritated by infection.

Frequent Urination at Night

Several papers show that having to urinate frequently at night is often caused by low levels of antidiuretic hormone (1,2) and that taking that hormone can control this condition.

Male Infertility

Infection is the most common cause of male infertility and that standard tests for infertility often do not find the infection. When evaluating a male for infertility, doctors check sperm count and sperm mobility. If a man's ejaculate contains fewer than 50 million sperm, he is infertile, and the most common cause of reduced sperm count is infection.

Male Hair Loss and Heart Attacks

A depressing study from Harvard School of Public Health showed that loss of hair on the top of the head markedly increases a man's chances of suffering a heart attack, and the more hair he loses, the more likely he is to suffer a heart attack (1). Men with male pattern baldness have higher than...

Baldness

Several years ago I reported that the present treatment for male-pattern baldness is not very effective and that male pattern baldness may be caused by insulin resistance, and that a diet high in sugar and flour may cause irreversible hair loss.

Prostate Biopsy Not So Benign

Doctors do not need to biopsy every man with a high PSA screening blood test for prostate cancer. Most patients become infected from the procedure, 20 percent suffer severe pain, 10 percent require strong pain medicines, and 15 percent of previously potent patients report that they can't get an erection one month later.

Swollen Testicles: Varicoceles and Hydroceles

Research has shown that most cases of swollen testicles do not need to be corrected by surgery. Swollen, painless testicles are usually caused by varicoceles, large veins full of blood on the outside of the testicles; or hydroceles, a sac of fluid around the testicles. Less common causes include infection or a tumor.

Bent Penis: Peyronie’s Disease

Three of 100 men suffer from Peyronie's disease, a bending of the penis during erection. The penis contains balloons that fill with blood to cause an erection. These balloons can develop a scar that prevents them from expanding normally during an erection, causing the penis to bend toward the scar.

Bicycling Does Not Raise PSA

A study from the University Hospital in Essen, Germany shows that riding a bicycle does not raise blood levels of PSA, the blood test used to screen for prostate cancer. Several studies suggest that ordinary bicycle seats can cause impotence which can become permanent with continued pressure on the nerves that control erection. Men who...

Zinc and Prostate Cancer

A study from the National Cancer Institutes showed that taking more than 100 mg of zinc supplements a day doubles a man's chances of developing advanced prostate cancer. There are hundreds of products on the market today that contain zinc and they are advertised to help treat the prostate, help prevent prostate cancer, help treat an enlarged prostate, treat impotence, increase sexuality, increase ejaculation volume, and make a man more potent. All of these claims are unsupported by scientific data.

Fitness Prevents Impotence

A study in the Annals of Internal Medicine (August 2003) showed that lack of physical fitness is a major cause of impotence. Dr. Eric Rimm of the Harvard School of Public Health showed that men who run for three or more hours per week, or play tennis five hours a week, have a 30...

Yeast Infections

When a woman develops a white discharge and vaginal itching, her doctor often diagnoses yeast infection, even though he may be wrong because every healthy woman has yeast in her vagina and cultures of the vagina almost always grow yeast, even in women who have no symptoms at all.

E. Coli Syndrome in Women

If you are a woman who suddenly develops burning on urination, have to urinate frequently and feel terrible discomfort when your bladder is full, or have urgency to urinate whenever your bladder is full, check with your doctor. You could have a bladder or a vaginal infection.

What is the best way to treat recurrent bladder infections?

When I was in medical school more than 45 years ago, I learned that E. Coli, a common intestinal bacteria, causes recurrent urinary tract infections in women; and that women with these infections should be given 100 ampicillin pills and be told to take one pill four times a day for three days, whenever...

How can I prevent wrinkles?

Unfortunately, there may not be much you can do; a study from Denmark shows that skin wrinkling and aging are influenced heavily by genetic factors.

Smoking Increases Cervical Cancer Risk

Cervical cancer is a venereal disease caused by the human papilloma virus called HPV. Nineteen different strains of HPV have been associated with cervical cancer. HPV-16 is the most carcinogenic. As solid cancers grow, they produce angiogenesis factors that increase blood flow to them to supply nutrients and energy. Tobacco contains nicotine, a potent...
