<s>[INST] 2 weeks before my grandmother had stroke and we consulted a neurologist , luckily we were able to give treatment at right time and she is not now paralyzed, now My grandmother is having serious dry cough, and the ESR is very high. she also have chest infection. Along with that she is having urinary infection and she is not able to take food also, Vomiting is also there. She was admitted and was given antibiotics, but no change, its getting severe. One day she will be alright, but next day she is weak. She has another complaint where her sodium gets reduced. [/INST] Hello, Thanks for the query, I have noted your problems. I am sorry that i donor know if she is on a urinary catheter which predisposes to urinary infections in patients with stroke. Basically we need to exactly pinpoint the type of infection in her so that she will respond to antibiotics. This can be done by urine culture-sensitivity test, culture for sputum and X-ray chest. These tests will be helpful in selecting the proper antibiotic and she will improve. Please check if she is on any medicine that can cause low sodium like HY Chat Doctor.  This is one of the common cause of low sodium. Stroke per se can cause low sodium Please consult a local physician who will guide you through investigations and treatment Hope this clarifies </s>
