### input:
My Eurasian mother is 91. Been bedridden with late age parkinsons and dementia. She is cared by us at home for 2 yrs. She cannot talk, can only make some grunts, can only move her eyes and her fingers flutter a little. Fed via nose tube fortified milk 7 times daily at 3 hour intervals. Since she is lactose intolerant we finally found Peptamine milk the best for her (no diarrhea). Has a catheter for urine and we have a nurse come in half a day twice a week. But my mother is doing pretty OK because her vital organs are rather strong. However, she produces a lot of phlegm and though she sometimes coughs (or sneezes out) the phlegm, we are quite concerned. We have bought a suction machine for the nurse to use. In between we give her chest physio (twice a week) and give her mucosolvan to dilute the phlegm. Any advise from you much appreciated. Thanks.

### output:

Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should rule out lung infection and bronchitis in your mothers case. She is not taking food orally. She fed via nasogastric tube. This can lead to micro aspiration of food particles in airways and lung. These can cause bronchitis and aspiration pneumonia. Both of them can cause excessive phlegm production. So better to consult pulmonologist for her and get done Clinical examination of respiratory system and Chest x-ray to rule out pneumonia and bronchitis. She may need antibiotics and inhaled treatment on the basis of these reports. Don't worry, she will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wishing good health to your mother. Thanks.
