If i were your doctor I would like to get a few tests carried out. If you sweat a lot, have resting tremors
and have more than average appetite and still losing weight I would like to have your thyroid
Secondly If that is not the case i would like you to increase your appetite.
Honestly speaking lesser your weight less prone you are to a number of diseases. Low weight individuals are less prone to develop hypertension
, cardiovascular disease
If you are exercising regularly, eating good food and dont have any of the symptoms i mentioned up there then i would just council you to not worry about your weight.
Just stay happy and be confident and remember you are less prone to a lot of diseases. but if u have any of the symptoms, it is recommended that you get a thyroid profile done!
Hope this answer was helpful.
If you need to know anything else i am always available
