Thanks for contacting HCM

I am sorry to hear that you are having episodes of passing out or near syncope when going from sitting to standing. This usually occurs when your blood pressure is low. By sitting your body blood pressure is stable and when you stand there is a lower of pressure. In most cases it is normal but if you have been experiencing this frequently then this would be abnormal and would require additional investigation by your doctor. I recommend since you are having these episodes frequently that you do seek medical attention.

Hope this answers your question. Please contact us again with your concerns.

Hi, welcome to our site. I am Dr Saumya Mittal, MD.

Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query

You have answered the query in your own query my friend.

First, it is definitely a matter of concern. Under no circumstances is it normal to have black outs. Its a matter of concern, and I would admit any patient I was seeing directly for further investigations and management.

Now, there are several possibilities why this may happen-

1, you dont eat right- you might have anemia- or low hemoglobin. This makes you weak because the oxygen carrying capacity of the body is reduced. You need to test a CBC with blood indices. If found to be positive, you will need to take iron and vitamin B supplementation. Correction of dietary habits is important of course.

2.There may be hypovolemia- low blood volume. This may be because of low water intake. The low blood volume means that when your body gets sudden stresses like standing from sitting position, the heart has to pump harder to keep the circulation ok. When it falls below that level where the heart cannot compensate further, the blackouts may happen. you just need to drink ample amount of water to cure this cause.

3. neurological and cardiological conditions need to be ruled out. Doing a MRI Brain, and an echocardiography would be a good idea of course. The treatment will be according to disease detected, if any.

I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further.

I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you.
