21.5 kgs loss in 6 months.chronic diarrhea/loose stools. easophagitis, gastritis, functional dyspepsia. in latest blood tests- globulin,protein are below range, and phosphate is above range. platelets,wbc,cholesterol are steadily dropping. reason?

If your weight loss was unintentional, as it seems, you ought to consult a GI specialist as you may have malabsorption of food and may have nutritional deficiencies. Wish you good health!

Your blood work is consistent with severe malnutrition and finding the actual diagnosis becomes critical. From malabsorptive states to infections and/or malignancies affecting directly or indirectly the gastro intestinal tract the work up should be expanded with your gastroenterologist or primary care doc being your best reference at this point.
