Hello! I read carefully your query and understand your concern. If I were your treating doctor I would advise to run some tests to exclude some possible conditions that can cause such symptoms. -Complete blood work to exclude anemia (low red blood cells and low hemoglobin). One of the most common medical reasons for feeling constantly run down is iron deficiency anaemia.Typically, you’ll feel you can’t be bothered to do anything, your muscles will feel heavy and you’ll get tired very quickly. -Blood sugar to exclude Diabetes or hypoglicemia.One of the main symptoms of diabetes, a long-term condition caused by too much sugar in the blood, is feeling very tired. -Thyroid function tests which include FT3,FT4,TSH to exclude low function of thyroid function (hypothyroidism). After have excluded these conditions your doctor can take in consideration other possibilities such as Chronic fatigue syndrome,Sleep apnoea which is a condition where your throat narrows or closes during sleep and repeatedly interrupts your breathing. This results in bad snoring and a drop in your blood s oxygen levels. The difficulty in breathing means that you wake up often in the night, and feel exhausted the next day. I suggest to consult a physician and get the tests done in order to sort out the right cause of your symptoms. Take care. Dr.Rovena
