What Causes Extreme Sleepiness And Weight Gain?
Information
Detailed Answer:
Hello XXXXXXX
I'm sorry you are having this problem. I have a few thoughts on this.
Gaining that much weight in 1 1/2 years is not normal and should be evaluated. Given the fatigue you are also having, it is important to check for thyroid disease with a thyroid panel (TSH, T4) which is a simple blood test.
Depending on what other physical features you may be having, checking cortisol and ACTH levels for adrenal gland function would also be a consideration.
Also a good idea to check a fasting blood glucose level or an A1C (checks average of blood sugar over previous 2 months) as diabetes can cause fatigue too.
Sometimes people gain a lot of weight from depression or from medications.
And, if you gain a lot of weight, it can interfere with good quality sleep, usually due to sleep apnea at night while lying in bed. This can cause daytime sleepiness. Diagnosis is with a sleep study (often these can be done from home now) and there is treatment for it.
So given this wide array of things to consider, I advise that you go in to see your doctor to evaluate what might be going on, and address that.
I hope this information helps. Please let me know if I can provide further information.
