Hello Mr. Chouhan, Your daughter seems to be suffering from dysfunctional uterine bleeding, a situation usually seen in many young people at this stage. You need to get her blood profile, complete hormonal profile, check for bleeding disorders and thyroid dysfunction. Obesity and anxiety may also cause this. Hormonal therapy should usually remedy the condition. If there is no response with simple progesterone, combination pills may be tried. Improve her general condition with good nutrition and maintenance of a healthy body weight. Please contact her gynecologist for further advice. Take care.
