Welcome to HCM, I am sorry to hear of your mom s excessive weight loss. Unfortunately, you are asking about a drink you did not identify. I might mention that you said she did not have sugar or BP , but was her thyroid status checked? It is highly unusual to just lose this much weight without some sort of disease process involved. You did not mention her appetite. It is important to distinguish weight loss that occurs while one is eating fairly normally and weight loss that occurs because the person has no appetite and is not eating food or drinking beverages. I suggest that she visit her family physician, have her thyroid checked, inquiry into her appetite and reasons for her weight loss and a treatment plan be developed in conjunction with a qualified dietitian. Best of luck to you, Kathryn Shattler, MS,RDN
