Feeling nausea or the feeling that vomiting might occur can be due to gut problems but more commonly is due to other causes...

Piles or hemorrhoids

  • Hemorrhoids are swollen veins that are normally present just inside the anus.
    • They can be considered to be normal “cushions”.
    • They can enlarge (because of increased pressure in the veins) simply as the result of straining or frequent defaecation.
    • They are often worse during pregnancy.

  • Gradually this high pressure can lead to enlargement of the veins.
    • Then there is the possibility of some protusion (proplase) of the hemorrhoids at the time of passing a bowel motion.
    • They usually withdraw back again but can stay out (sometimes causing discomfort) and may need to be pushed back.

  • The main symptom of hemorrhoids is bleeding.
    • This is bright red bleeding noted on the toilet paper.
    • Or there is a “dripping” or ”squirting” of blood that can splatter in the toilet bowl.
    • If there is some protusion of inflammation of the hemorrhoids there can be discomfort or pain of defaecation.
    • Usually there is bleeding without pain.
    • Another type of problem is the external hemorrhoids. There can be a clot forming in the vein and this gives a painful firm lump that is easily felt.

Diagnosis and treatment.

  • Rectal bleeding should never be dismissed as simply hemorrhoids without a proper examination.
    • This requires passing a tube into the rectum to examine the bowel (sigmoidoscopy).
    • For people older than 40 years it is important to perform a colonoscopy to have a complete inspection.
    • Colonoscopy may be required at an earlier if there are concerns about the nature of the bleeding or other symptoms.
    • Specialist review may be required.

  • The use of cream and/or suppositories can reduce the associated inflammation and may reduce discomfort and reduce bleeding.
    • Anusol ointment and suppositories are commonly given.
    • Some continued bleeding can be accepted so long as a thorough examination has been performed.
    • Discomfort around the anus may be an associated symptom (see pruritis ani).

  • Reducing straining by treatment of constipation is the important approach.
    • Increased fibre is usually the best approach but other treatments as outlines in the constipation section will also be helpful.
    • However there are other ways of improving bowel habit if fibre causes problems such as bloating.
    • If diarrhoea and bowel frequency is the problem then appropriate diagnosis and treatment is requires.
    • Avoid prolonged sitting and straining on the toilet.

  • If the bleeding continues then surgical treatment is required.
    • This can be simple injection treatment or banding which can be performed in an office setting.

  • If there is significant prolapse of the hemorrhoids or failure of simple treatment then an operation under general anaesthetic may be required.
