Thanks for writing in.
I suggest you to have a general medical check up including a complete blood checkup and X ray chest.it would be. worthwhile to do an ultrasound
scan and ECG too. A fasting and post prandial sugar level assessment will help to rule out diabetes
. Once the above tests are done and results are found to be normal, please do not worry about heart, diabetes and cancer related problems.
If any tests are positive, treatment is available for most diseases. Increase in weight and appetite can be solved by allowing your mind to be free from stress
. If your anxiety
and stress are too much then please consult a psychiatrist
Hope this helps
