Sheldon G. Sheps, M.D.
Dr. Sheldon Sheps, emeritus professor of medicine and former chair of the Hypertension Division in the Department of Medicine at Mayo Clinic, has been with Mayo Clinic since 1960.
Dr. Sheps, a Winnipeg, Manitoba, native, is board certified in internal medicine and specializes in hypertension and peripheral vascular diseases. He developed a multidisciplinary approach with specially trained nurses, dietitians, technicians and educators to help form a team approach to the treatment of patients with abnormal blood pressure.
"I have always believed in involving the patient and family in their health care," he says. "I have asked for their understanding of the illness and issues and for participation in decisions. The Web is a natural extension of that, and now many more people can be informed."
Dr. Sheps chaired the sixth working group, and participated in the fourth, fifth and seventh groups, that developed the then-latest guidelines for hypertension under the auspices of the National Heart, Lung and Blood Institute (NHLBI). He helped write the latest American Heart Association (AHA) report on blood pressure measurement. He chaired an AHA group that produced an online accreditation for blood pressure measurement for health professionals. He has co-authored books, newsletters, CD-ROMs and other Mayo Clinic health information material and joined Mayo Clinic's Web team in 1998. He was editor-in-chief of both editions of the "Mayo Clinic on High Blood Pressure" book; the last edition was published in 2003.
He was section editor for each of the first three editions of "Hypertension Primer" for the American Heart Association.
Dr. Sheps was also chairman of the Science Base Subcommittee, National High Blood Pressure Education Program, and was a consultant to the Hypertension Initiative of the World Health Organization. In 1997, he was honored with the Individual Achievement Award on the 25th anniversary of the National High Blood Pressure Education Program of NHLBI.

Foot swelling during air travel: A concern?
What causes leg and foot swelling during air travel?
Answer
from Sheldon G. Sheps, M.D.
Leg and foot swelling during air travel is common and typically harmless. The most likely culprit is inactivity during a flight. Sitting with your feet on the floor for a long period causes blood to pool in your leg veins. The position of your legs when seated also increases pressure in your leg veins. This contributes to foot swelling by causing fluid to leave the blood and move into the surrounding soft tissues.
To relieve foot swelling during a flight:
- Wear loosefitting clothing.
- Take a short walk every hour or so.
- While you're seated, flex and extend your ankles and knees often.
- Shift position in your seat as much as possible, being careful to avoid crossing your legs.
- Drink plenty of fluids to prevent dehydration.
- Avoid alcohol and sedatives, which promote immobility.
Foot swelling isn't a serious problem if it lasts only a short time. But excessive swelling that persists for several hours after you resume activity may be due to a more serious condition, such as a blood clot in the leg (deep vein thrombosis) — especially if the swelling occurs in only one leg and is accompanied by leg pain. If you experience these signs and symptoms, seek prompt medical attention.
If you're at increased risk of blood clots — you recently had major surgery or you take birth control pills, for example — consult your doctor before flying. He or she may recommend wearing compression stockings during your flight. In some cases, the doctor may prescribe a blood-thinning medication to be taken before departure.
