Hi, Welcome to Health care magic forum.
After stopping the breast feeding, there will be increase in
estrogen, and other changes in the body, which may cause the
pimples, but loss of weight may not be due to stopping the feeding.
The cause may be diet restriction, loss of appetite, or some chronic disease like
tuberculosis.
I advise you to consult a physician for diagnosis and treatment .
Your doctor may prescribe, injection of
anabolic steroid, periodically, enzymes, multivitamins, and
protein supplements till the diagnosis is established.
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods, also take more calories, fats, fries, ice creams etc.
Wishing for a quick and complete recovery. Thank you.
