I am 26yrs old, female, I woke up after sleep as usual, and suddemly had sinking feeling in my heart, I felt dizzy, and had a sudden bout of presipitaion through my body and some bitter secretion in my mouth. Days later, I started getting more tired than usual, and have this sinking feeling in heart more often and dizziness. although I am not falling unconscious, because I sit down immediately and regain full consciousness soon. Thanks !
There could be a number of reasons for your symptoms.1. It could be due to anxiety or depression, are you currently facing some challenges in your personal life? 2. it could be due to anemia in which case you need to check your he and if it's lower than normal then you might need to include certain things in your diet like milk, apples, dates etc., and you might need some supplements. 3. if your married or in a relationship, when was your last period?  It could be due to pregnancy 4. Do you have any congenital heart disease or were you born premature?  Or if your from a developing country have you ever had rheumatic fever?  In these cases you might want to book a visit to your physician who could do some baseline investigations like ECG and echocardiography. 5. if its none of the above check for any alarming associated symptoms and if your condition doesn't resolve soon or gets worse it would be better to give your physician a visit.
