When to seek further review
- Speak to a pharmacist if simple changes are not enough. Most laxatives work within about 3 days; ask for advice if they are not helping rather than repeatedly increasing the dose yourself.
- Arrange GP review if constipation is not improving with treatment, keeps returning, or there is an unexplained change in bowel habit.
- Arrange review for blood in the poo, unexplained weight loss, persistent tummy pain or marked tiredness.
- Seek urgent advice today for worsening pain, vomiting or increasing tummy swelling.
- Do not wait for the suggested review time if symptoms become worse, new symptoms appear, or you are worried.
- Contact your GP when the surgery is open. If it is closed, you cannot get the help you need, or you are unsure what to do, call NHS 111. You can call even if you are not sure whether the symptoms are serious.

How to spot sepsis
Sepsis is a life-threatening reaction to an infection. It can get worse quickly. If someone is seriously unwell and may have sepsis, call 999 or go to your nearest Emergency Department. Do not wait for every sign, a high temperature or a rash.
An unwell child under 5 who has not had a pee or wet nappy for 12 hours needs emergency assessment. If you are unsure and there are no emergency signs, call NHS 111 for advice.
