Treatment for Diarrhoea

If you suffer from diarrhoea, there are different treatments available to help you get on with your day as normal. Learn why, when and how to treat diarrhoea.

Why treat diarrhoea?

Diarrhoea can cause discomfort, inconvenience and disruption to your day-to-day life. Without any treatment, you may feel weak, lack energy and experience uncomfortable symptoms that can affect your plans – whether it’s work or socialising.

Imodium helps your body retain water and essential nutrients.

There’s a common myth that it’s better not to treat diarrhoea, instead letting it run its course. But why leave it untreated when you can relieve diarrhoea, get on with your day, and help reduce the loss of fluids and salts that can leave you feeling weak and tired? Imodium can help restore your body’s gut rhythm gently.

However, you should speak to your doctor before using Imodium if the diarrhoea is particularly frequent or severe, or associated with other symptoms, such as:

  • blood in your stool or fever
  • persistent vomiting
  • a severe or continuous stomach ache
  • weight loss
  • signs of dehydration – including drowsiness, passing urine infrequently, and feeling lightheaded or dizzy
  • your stool is dark or black – this may be a sign of bleeding inside your stomach

Do not take Imodium for more than 48 hours. Not for children under 12 years.

Causes of diarrhoea

Diarrhoea is caused by a disturbance to the normal absorption of fluids by your digestive system – essentially, your digestive system works too quickly . This means your gut doesn’t absorb enough fluids and so they remain in the gut and cause your stools to become runny. . This can lead to an unbalanced bowel and cause dehydration . Read the leaflet carefully before using Imodium.

Diarrhoea occurs when you experience looser or more frequent stool than is normal for you . Acute diarrhoea usually lasts from a few days to a week. Chronic diarrhoea typically persists for more than 4 weeks. This can be caused by an underlying medical conditions and so you should consult a doctor.

You should treat the root cause of diarrhoea where possible – such as avoiding certain trigger foods or factors you know can result in you getting diarrhoea.

The main causes of diarrhoea include:

Effects of diarrhoea

When you experience diarrhoea, the lining of your intestine fails to absorb sufficient fluids. This leads to your body passing more liquids than it should.

Such a high loss of fluids doesn’t just mean your body loses water but also the important minerals and electrolytes contained within them that keep your body running. As your body doesn’t absorb these nutrients properly, diarrhoea can also cause:

  • Electrolyte and salt deficiency

It can put you at risk of dehydration. Symptoms include:

  • Dry mouth
  • Decreased urination
  • Fatigue
  • Dizziness and light-headedness
  • Thirst
