At other times I feel like vomiting please help what do you think it could be... I ve also just started feeling this way for maybe about a week now [/INST] Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion we should rule out cardiac cause first for your symptoms. Because hypotension can cause breathlessness, giddiness, dizziness and vomiting. So better to get done1. Ecg2. 2d echo. If both are normal then no need to worry much for cardiac cause. Get done chest x-ray and PFT (pulmonary function test) to rule out pulmonary cause like bronchitis. So better to consult doctor and discuss all these. First diagnose yourself and then start appropriate treatment. </s>
