Hi,
Loss of weight usually occurs due to diabetes, celiac disease(
autoimmune disease),
hyperthyroidism, cancer, RA, poor diet (anaemia) resulting in independent oedema.
While diarrhoea for a long time is indicative of Inflammatory bowel disease( Crohn's disease, colitis),
Irritable bowel syndrome, lactose/glucose intolerance.
Visit a PCP, get health check-up done along with all required screening tests to evaluate the developing pathology. CBC, Urinalysis, Imaging tests, etc.
In the meantime take Lomotil,
Rabeprazole, Spasmol & some
multivitamin supplement. Stay well hydrated & take home made food.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Nupur K, General & Family Physician
