Man who was drinking 'far too much water' gets devastating diagnosis after eye test

A postman who was drinking 10 litres of water every day for two years was given a heartbreaking diagnosis following an eye test. Doctors initially thought Jonathan Plummer had diabetes.

The 41-year-old had been suffering with a 'constant thirst'. But appointments with his GP and a kidney specialist resulted in inconclusive test results.

Instead, a routine eye test discovered a 'mass'. Jonathan was referred to hospital for an MRI scan and diagnosed with a brain tumour.

He said: "I felt a constant thirst that I couldn’t quench and got to the point where I was passing as much water as I was drinking. It was an awful time which caused me to miss days of work at a time and I experienced extreme fatigue."

The tumour was on Jonathan's pituitary gland, which impacts water retention. Jonathan underwent 30 rounds of intense radiotherapy.

"I was devastated. The tumour was growing on my pituitary gland - which was causing my need to drink water all the time - and many other ‘spots’ on my brain.

"An operation wasn’t an option so I was placed on steroids to help with the pressure of the tumour in my brain.” Jonathan, from Falmouth in Cornwall, was diagnosed with a germ cell tumour back in 2002.

He had steroid therapy which caused him to gain four stone - going from 12st to 18st. Jonathan said: “I was always very active and played rugby and cricket weekly which is something I have never been able to return to.

"I took up running and swimming as non-contact exercise and have regained control of my weight.” Now cancer-free, Jonathan remains on life-long medication.

He will soon be doing a sponsored skydive to raise money for Brain Tumour
