<s>[INST] Hi! For a bout a week now I have been feeling so exhausted and tired it takes me till the middle of the day to feel normal, and then around 3pm I feel so tired my eyes literally start closing whilst I am at my desk, and I find it so hard to fight. I have noticed that I am short of breath and feel really tight in my chest, and only occasionally have a bit of nausea but it doesnt last long. I excersice regulary and eat as best I can. My mother had Amenia, is this hereditary as I have researched the disease? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Yes, anemia can cause all your symptoms. Anemia is low hemoglobin. Most common cause for this is dietary deficiency of iron and folic acid. There are certain genetic causes for anemia, but they are very rare. So first get done CBC (complete blood count), serum iron and folic acid level. This will tell you if you have anemia or not. You may need iron and folic acid supplements if they are low. If your CBC is normal then possibility of stress and anxiety related symptoms is more likely. So avoid stress and tension, be relaxed and calm.Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
