DEAR DR. ROACH: I had symptoms of lightheadedness, so my doctor ordered an EKG and sent me to a cardiologist. They did a heart monitor for a week and said I have inappropriate sinus tachycardia but that I don’t need any treatment. I’m still having symptoms. What can I do? – B.V.
ANSWER: Inappropriate sinus tachycardia is an uncommon diagnosis, most often seen in women in their 30s. The heart rate is fast (“tachycardia”), but on an EKG it appears normal, meaning it comes from the sino-atrial node, the natural pacemaker of the heart, hence “sinus.” The average heart rate must be over 90 for 24 hours.
It’s important to be sure there isn’t another cause for the tachycardia, such as elevated thyroid levels, fever, volume depletion (dehydration) or anemia. The symptoms may continue for months or even years. Common symptoms include the lightheadedness you felt, but may also include palpitations, shortness of breath, dizziness and decreased ability to exercise.
The diagnosis can sometimes be confused with POTS (postural orthostatic tachycardia syndrome), where the heart rate dramatically increases with changing to an upright position. A tilt-table test is the diagnostic tool for POTS.
If there is no other reason for sinus tachycardia, then medication may be used to reduce symptoms. A beta blocker is the usual first choice, but there are others available.

DEAR DR. ROACH: I am a woman going crazy with hair loss. My hair has always been long and thick, but it is coming out in handfuls. I can only think it must be due to my blood pressure medicines. I’ve been taking amlodipine and lisinopril for years. I’m in good health and 90 years young. – M.
ANSWER: It is unlikely that the hair loss is due to either amlodipine or lisinopril. Neither of these are well described to provoke hair loss, and if a medicine is going to do that, it usually does within a few months.
The most common cause of hair loss in a 90-year-old woman is female pattern hair loss, in which the hair loss is mostly on the front and top of the scalp. However, there are several causes of hair loss, and a dermatologist may be helpful in determining the cause and treatment.
Please don’t stop taking your blood pressure medicine.
DEAR DR. ROACH: I have a question about undigested food. Are you getting any nutrients, other than fiber, from foods that come out looking the same as they went in? I’m thinking of foods such as corn and sunflower, flax or chia seeds. How well do they need to be chewed to get any nutrition from them? – L.W.
ANSWER: Many seeds and corn need to be chewed very well in order to be absorbed by the body. They have a large amount of undigestible fiber, which will never be absorbed. Chia seeds, unlike flax or sunflower seeds, are pretty easily digested by most people, but you can grind them and soak them ahead of time to make it easier for your body to digest them.
