Let us understand the complications of overuse of prescription laxatives in detail and know various natural laxatives.


What is constipation?

Constipation is a condition wherein an individual has hard feces which are difficult to expel. It generally occurs when too much water is absorbed from food, making the feces dry.

Constipation can be acute, due to certain medications or consumption of milk products. Chronic constipation occurs when there is less intake of water, less physical activity (1). Aging is also related to constipation as the bowel movements get slow and sluggish.

Pregnancy brings about hormonal changes that can increase the chances of constipation.  Also, the enlarging uterus may compress the intestine, making it difficult for passage of stools (2).

Complications of constipation

Constipation is uncomfortable and can cause irritability. However, chronic constipation can develop into more serious conditions, including:

  • Anal fissure, or a small tear around the anus
  • Rectal bleeding after straining to pass stools
  • Hemorrhoids, or swollen, inflamed veins in the rectum
  • Fecal impaction, in which dried stools collect in the anus and rectum causing an obstruction (3).

What is laxative?

Laxatives are the products which tend to increase the stool motility, bulk, and its frequency. It is prescribed to provide relief from constipation. Laxatives come in various forms like pills, capsules, and liquids, suppositories and enemas.

Do you know that there is a difference between stool softener and laxative? The stool softener is a type of laxative (Emollient Laxative). The other way around is not true. So, all stool softeners are laxatives but not all laxatives are stool softeners. In fact, there are several types of laxative. Each type of laxative has specific benefits and possible side effects.

Emollient Laxatives or stool softeners

These laxatives contain a surfactant that helps to soften the stool and are often called as stool softeners. Emollient laxatives take few days to be useful and complete its action to soften the stools.

They are prescribed to individuals with hemorrhoids, those recovering from surgery, women who have just given birth.

Bulk-forming laxative

These laxatives contain active ingredients as methylcellulose, psyllium, and calcium polycarbophil. They form a gel in the stool which in turn helps it hold more water. The density of stool increases and thus intestine pass it easily and quickly.

They have little risk of side effects and can help people with chronic constipation. Also, they take longer than other laxatives to work. But if you are planning to use them for a longer period then you should consult your doctor.

Lubricant Laxatives

They contain mineral oil which makes the stool pass through without any obstruction. The oil prevents the stool from drying out. Lubricant laxatives should be used as a short-term cure for constipation as the mineral oil can absorb fat-soluble vitamins from the intestine.  Lubricant laxatives also decrease certain prescription drugs from being completely absorbed into the body.

Osmotic and Hyperosmolar Laxatives

These laxatives work on the principle of osmosis; they draw fluids from the surrounding tissue into the intestine. The increase in the water content in intestines results in softer stools which are easier to pass.

While on osmotic and hyperosmolar laxatives it is crucial to increase the daily water intake as it can cause gas and flatulence.

Guanylate Cyclase-C Agonist Laxatives

This type laxative changes stool consistency by increasing the amount of water into the GI tract and increases gastrointestinal movement. It is a prescription laxative for those suffering from chronic idiopathic constipation.

These laxatives should be taken only on prescription and are not recommended for patients younger than six. They also carry a risk of diarrhea and dependence.

Stimulant Laxatives

These laxatives are quick acting and provide steady results hours into consumption (4). They stimulate the lining of the intestine which accelerates the movement of stool through the colon.

Stimulant laxatives also soften the stool. This type of laxative may weaken the body’s natural ability to defecate and cause laxative dependency while increasing the risk of diarrhea.

What are the side effects?

Bloating, gas, cramping, stomach upset, abdominal pain, flatulence are the common side effects of laxatives. Some people abuse laxatives to lose weight, and when a person takes higher or more frequent doses of laxatives, it can result in severe complications.

  • Chronic constipation, due to damage of cilia of the intestine
  • Laxative dependence for even regular bowel movements
  • Severe dehydration and electrolyte and mineral imbalances
  • Internal organ damage
  • Increased colon cancer risk

Over-the-counter laxatives can be a quick fix in alleviating constipation. But using these prescription stool softeners more often can cause the change in acid-base balances and electrolyte disturbances. In the long run, there could be potentially serious consequences such as heart and kidney damage (5).

Natural laxatives are the best method to treat constipation as it does not cause dependence and is healthy for the cilia of the intestine.
