What causes excessive sleepiness and breathing difficulty?

Brief Answer: get your thyroid tested Detailed Answer: Hello XXXXXXX Please get your thyroid function test (TFT) done that includes T3, T4, and TSH. Under functioning thyroid or Hypothyroidism is the most common cause of your symptoms. Also, it could be due to less physical activity or more mental strain. Either ways, you should take care now. If you are in mental strain, please come out of it. If it is physical inactivity, I would suggest you to work out in the evenings. Try going for an early morning walk, you will feel better. Feeling sleepy all day is not a good sign, it suggests your lack of interest in daily activities as well. Get the test done as advised. Regards,
