Hi, my blood pressure has decreased over the last few months and has been quite low in the last few days. My personal trainers were concerned and did an ecg to check heart and blood pressure. Blood pressure was 88/68, ECG was fine. Saw my GP yesterday and it was 110/?? but he said it wasn t too low and recent blood tests showed normal results. I m currently being treated for neuroendochrine tumour so have had lots of diarrhoea in the last few months. I think that may be the cause of the low blood pressure. Oncologist said tumours would not have affected my blood pressure. I am drinking plenty of fluids. The diarrhea is not constant so wondering if I should take some medication to stop the diarrhoea. I normally suffer from constipation and have haemorrhoids.

Summarized question: What causes low BP while treating neuroendocrine tumor?
