Where is the constriction? What is weight that was lost and in what duration? What are the memory problems? Any other associated symptom? Any daily medications? Which surgery was done? Was any other investigation done such as complete blood count? Was there a decrease in the hemoglobin level?
These symptoms are unlikely to be due to malabsorption in view of the normal blood counts and also constipation. However the causative factor for these symptoms needs to be investigated for and then treated. Losing weight without trying is a warning symptoms of an underlying disorder. This weight loss along with other symptoms may be due to an overactive thyroid (hyperthyroidism), diabetes, depression, liver disease, cancer, or neurological disorder. Please consult a good internal medicine physician who will do an examination and relevant investigations based on the examination. He/she may then refer him to a specialist based on the results of the investigation.
