Brief Answer:
Need to know your medicines

Detailed Answer:
Thanks for your query.

I have read your query. Your main concern at present is that you do not feel energy.

I need to know more details about the symptoms like when it started, do you feel breathless on exertion, what brings it on, medicines you are taking, etc.

If you are able to provide more details about it, I will be better able to help.

Waiting for your response.

Brief Answer:
Get an echo of your heart done

Detailed Answer:
Hi again.

You have not mentioned if an echo was done. Was there any abnormal heart sounds heard on auscultation by the doctor? Echo helps rule out any structural heart conditions.

You will consistently need to monitor your blood pressure as it may be fluctuating. Get the basic blood tests done including thyroid profile, complete blood counts, serum electrolytes. Can you upload the reports of the blood tests that were done already?

You will need to go on low salt, low sugar and high fruit diet. You will also need to take hygienic food and clean drinking water. Do some mild exercises and do not overexert.

I do not know the reason why it happened the first time. It is hard to predict if it will happen again. But you need to relax as worrying can raise the BP.

Hi, My wife had a dermoyd cyst removed a few year ago and with it her left ovary. Every since then, she has had a really hard time during her period. Lately, she has experienced a rapid heart rate. She is 23 years old and 105lbs. Generally healthy but she is a smoker. She rarely drinks alcohol and doesn't do any drugs. Her water intake is good as is her diet. She doesn't feel any stress, although, our life is rather stressful. She is anemic and has low blood pressure and her heart rate averages around 100bpm during her period. Is this something we should worry about?
