One of the most common digestive complaints, severe constipation affects more than one in 200 women in the UK.

While there is great variation between individuals, most cases of constipation result from too little fiber or dehydration. While symptoms vary between people, the most common symptoms of constipation include:

Stomach pain and cramps
Bloating
Nausea
Fluctuations in bowel movements
Constant feeling of fullness
Headaches
Furred tongue
Loss of appetite
Fatigue
Depression

Ironically, constipation can sometimes alternate with diarrhea - this is often a symptom of another condition such as Irritable Bowel Syndrome (IBS).

There are a variety of causes. In addition to lack of fibre and dehydration, other causes include:

Sedentary lifestyle
Medications, including painkillers, antidepressants, and antacids
Excessive use of supplements such as calcium or iron
Pregnancy
Excessive consumption of tea or coffee
Dieting
Weak bowel muscles
Recent abdominal surgery

Treatment will depend upon the diagnosis, so it is essential that you consult your doctor. Options include:

Increased intake of fibre - ideally 20-30g a day
Increased fluid intake (water)
More exercise

Your doctor may suggest a short course of drugs (stool softeners and laxatives), but these are only a temporary measure and should always be accompanied by changes in lifestyle to ensure that the symptoms don't return.
