Sensitivity to beta blockers

My husband had open-heart surgery last spring. Since then, even putting his clothes on makes him so breathless he can barely speak. He is weak and exhausted all the time.

I checked online and found that metoprolol has a warning to contact the doctor immediately if you experience wheezing, shortness of breath or swelling of hands and feet. He has all those symptoms.

Can this medication cause these symptoms?

Metoprolol is a beta blocker that helps prevent the heart from overworking. It can also lower blood pressure.

Some people are sensitive to such medications and develop wheezing or difficulty breathing. This is a serious reaction that deserves immediate medical attention.

Your husband should consult a lung expert (pulmonologist) as soon as possible.

The swelling of hands and feet merits a prompt evaluation by a cardiologist.

I have a question about a dietary supplement called konjac. It is recommended for controlling blood sugar and assisting with weight loss. Do you know anything about this product?

Konjac, or glucomannan, is made from a Japanese root vegetable. It absorbs water and is sometimes used as a laxative.

Glucomannan contains insoluble fiber that slows the absorption of sugars from the digestive tract. Some studies show that it helps lower blood sugar in Type 2 diabetics. It can also lower cholesterol. Its usefulness for weight loss has not been firmly established.
