Hello speedbird,

Thank you for getting in touch and welcome to the Online Community.

I’m sorry to read that your husband’s symptoms are worsening since he completed his radiotherapy in January.

It’s important that your husband is reviewed by his GP today to make sure he is not becoming dehydrated due to fluid loss.

The GP can prescribe medication to lessen the diarrhoea and check if your husband has any sign of infection.

If you cannot speak to the GP today, then we would suggest contacting 111 to discuss your husband’s symptoms.

It might also be worth getting in touch with the hospital to ask if there are specific diet instructions for people affected by diarrhoea after radiotherapy. If your husband has been allocated a clinical nurse specialist or a key worker, this is who you should contact.

Unfortunately, a change in bowel habits can occur after radiotherapy to the pelvic area, but it’s a concern that your husband’s symptoms are getting worse.

If your husband has any of the following symptoms, then we would suggest calling 999:

Increasingly tired or weak

Confused or disorientated

Dizzy when standing up that doesn’t go away

He has not passed urine in 8 hours

His pulse is fast or weak

Feels as if he is going to pass out


I do hope your husband feels better soon and dont hesitate to get back in touch if you have further questions.

Best wishes,


Cancer Information Nurse Specialist

Thank you for replying to me, J has taken Imodium and diarrhoea is finally under control. He took a blood test last week which found him to be anaemic and have kidney failure, we are waiting for him to see a oncologist for follow up, but is it normal to have kidney problems after  radiotherapy for bladder cancer?  It seems we are experiencing so many problems and it is difficult to sit by and watch him suffering. He has the number of the Health Care team but will not call them.
