Hi doctor, I am 28 year old. My sugar level is normal, TSH is 2.91 and cholesterol is 203. I am facing a problem with my pulse rate. It is between 115-120 when I walk or do any activity. But when I am in rest, it ranges between 80-100. I feel lightheadedness when I walk. Is it normal?
Hello. Cholesterol is in upper borderline. It will come down with low cholesterol diet and exercise daily. Heart rate more than 100 while walking is fine. From your history lightheadedness is the only problem. Is this lightheadedness significant? Do you feel like falling or black out? Monitor your BP (blood pressure) while feeling lightheaded. Measure your BP while sitting followed by standing after three minutes. Sometimes people have positional hypotension. Also, do a Holter monitoring (24 hour ECG) with normal activity whole day. So, we can see your heart rhythm pattern while lightheadedness and rapid heart rate.
