Hello everyone , would like some advice please . 

In the last 3 months since my last transplant ( renal) clinic check up , I have shed approx 4kgs in unplanned weight loss. 

I have to clear my throat often and my voice sometimes changes while talking . I also have a light cough and hiccup daily.

Really conceren that my acid reflux has turned serious .

I hadnt given it much thought until my trousers and jean belt went down a notch and weighed myself at work .

Becoming more concerned as this day progresses as it's all pointing to a more sinister diagnosis 

Than you very much for any advice
