Hello Thanks for posting at HCM. I have gone through your description. So the issues she has are kidney dysfunction, dialysis dependent and fluid in lungs secondary to fluid overload. Intolerance to liquids can be due to esophageal problems (food pipe). So a gastroenterlogist needs to be involved and a endoscopy of the stomach has to be done. further action depends upon the findings in endoscopy. Putting a tube in the chest to remove fluid from lungs can provide rapid relief of symptoms and also the fluid can be tested to find exact cause of accumulation and presence of infection. In the meanwhile you should give fluids via straw which she will tolerate better. Also please don t continue feeds if she coughs while eating or drinking. Wishing her good health Regards
