I have recently had bloodwork donw because I am a suspect for PCOS. I get the results Friday but I am curious…if this is in fact a hormone imbalance, will they give me a medication that will reduce the problems I am having (i.e. witch hairs, skin tags, acne). thanks for your help!

Sometimes when I play tennis in the hot sun (90-105) temperatures for a while (2-3 hours) I get the chills, especially in my arms…the hairs on my arms stand up… and the chills come maybe just once or twice and then go away. are the chills a symptom of some sort of heat stroke/heat exhaustion? I don't have any other symptoms besides those that are common when one exercises a lot. oh and later at night I feel very hot and sweat sometimes i even get hot flashes. I do and drink a lot of fluids while playing of course

Dear Dr. Donohue: in 1970, when in college, I had a friend who bruised so badly that she looked like a battered woman. The doctor at the health care center told her to take vitamin C because it strengthens cell walls. she did, and the bruising stopped.

My father died of ischemic stroke and had suffered from heart disease. My mother has had several hemorrhagic strokes. I am 60 and started taking baby aspirin. I am bruising more. I am thinking about adding vitamin C to my program. will it interfere with the baby aspirin’s blood-thinning effect?

Dear N.L.: Ever hear of scurvy? It’s not seen much these days, but in the 15th through 18th centuries, it was a common disorder and was rampant among sailors. Dr. James Lind, a British naval surgeon, experimented with groups of sailors, giving them a variety of treatments. The group given a daily lemon and two oranges recovered quickly from all the signs and symptoms of scurvy. those signs are small and large bruises, bleeding from the gums, coiled hairs, joint pains and impaired wound healing. perhaps this was behind the college doctor’s prescription of vitamin C for your friend.

Vitamin C is involved with the synthesis of collagen, one of the major support tissues in the body. It’s a powerful antioxidant, neutralizing oxidants, which are byproducts of cell metabolism that wreak havoc in the body. It aids in the absorption of iron. It keeps the immune system healthy. It stops the bleeding and bruising of scurvy by strengthening capillaries, the smallest of blood vessels. I find no information that it interferes with aspirin’s anti-platelet effect. Platelets form clots that sometimes occur in arteries and obstruct blood flow. The result can be a heart attack or a stroke.

With your mother’s history of hemorrhagic (bleeding) strokes, you should consult your doctor before launching into daily aspirin.

Dear Dr. Donohue: My 51-year-old son has been diagnosed with a Zenker’s diverticulum. he has seen many specialists, but none has spoken of a cure. he has difficulty swallowing. Is there any relief?

Dear M.F.: The loss of tissue elasticity, along with weakening of the swallowing muscles, sets the scene for the bulging of the throat lining through the throat muscles to create a pouch. That’s a Zenker’s diverticulum. Food gets caught in the pouch, and no effort on a person’s part can dislodge it. Difficulty swallowing and an increased production of saliva result. Food decomposes in the pouch. Eventually it’s regurgitated into the mouth and creates a foul odor.

Surgery corrects the situation. A newer technique is the use of a flexible scope, introduced through the mouth, that permits repair without an incision.

Dear Dr. Donohue: I am a 63-year-old male. I work out three or four times a week, doing aerobic exercise and weight training. during a routine physical, I was diagnosed with low testosterone. My doctor scheduled me for bimonthly injections in his office.

Recently a friend told me that her husband was diagnosed with low testosterone and that his doctor prescribed a pill. Is testosterone available as a pill?

Dear T.V.: Testosterone is available as a pill. however, oral testosterone isn’t the best way to correct a deficiency. It doesn’t reliably provide sustained blood levels of the hormone. To overcome this obstacle, doctors choose other methods of delivering it or prescribe a testosterone that has been chemically altered.
