Nerve problems

Nerve damage and pain

Type 2 diabetes means you are more likely to get nerve damage, or neuropathy. Neuropathy can cause pain – this is called neuropathic pain. See NICE's guidelines and information for the public on medicines for neuropathic pain.


Gastroparesis is a type of nerve problem that affects the stomach. It can make you feel full and bloated even after eating a small amount of food, and can cause vomiting.

Your doctor may also offer you medicines to help with vomiting – if so, they should explain about the possible risks and benefits of taking these medicines.

If these treatments do not help or aren't suitable for you, you may be referred to a specialist.

At the time of publication, some medicines for treating gastroparesis may be recommended for off-label use in this guideline. Your doctor should tell you this and explain what it means for you.

Questions to ask about gastroparesis

  • What causes gastroparesis?

  • What can I do to reduce or stop vomiting?

  • What medicines can I try? How will they help?

  • What are the side effects of these medicines? What should I do if I get any side effects?

Erection problems

Erection problems (also called erectile dysfunction) are quite common in men with type 2 diabetes. If you wish, your doctor or nurse should talk to you about this at your annual review. If you would like treatment you should be given medicine that can help, if this is suitable for you. If this doesn't work, your doctor can refer you to a specialist clinic.

Other nerve-related problems

Talk to your doctor or nurse if you have diarrhoea (particularly at night) or problems emptying your bladder fully. Also tell them if you are worried about other symptoms such as sweating a lot, or if you start to have hypos without the usual warning signs. These symptoms may be caused by nerve problems, and you might need further tests and treatment.
