Pro/Cons of an Eating Disorder


The list of cons is much longer than the pros.  The pros are highlighted below in red.  Some constipation, fluid retention and weight gain are a small price to pay to give up……

Physical Consequences and Complications


The most common consequence of laxative abuse is dehydration. Significant water loss is a side effect of diarrhea and can pose a great health risk. Symptoms of dehydration range from dizziness, weakness, confusion, fainting, and prolonged dehydration can lead to death.

Electrolyte Imbalance

Laxatives work near the end of the bowel and impact not only absorption of water but also crucial electrolytes such as sodium and potassium. Electrolytes are necessary to maintain nerve and muscle function throughout the body.

By depleting the supply of electrolytes, the imbalance in the body can lead to:

  • Low blood pressure
  • Confusion
  • Tachycardia (rapid heart rate)
  • Trembling
  • Muscle weakness
  • Stiff and achy joints
  • Sunken eyes

Prolonged and severe electrolyte imbalance can lead to shock, cerebral edema (swelling in the brain), seizures, and coma (Eating Disorders Review, 1999).


As laxatives cause the loss of fluids, the body responds by trying to protect itself from dehydration and ends up retaining fluid.

Edema is the swelling of the fluid buildup and can decrease flexibility of the joints, cause tight or stiff skin, pain and difficulty walking, and decrease blood circulation.


Individuals may notice blood in their stools after excessive use of laxatives. Chronic blood loss can result in anemia. Symptoms of anemia include:

  • Exhaustion
  • Irregular heartbeat
  • Chest pain
  • Shortness of breath
  • Dizziness
  • Cold hands and feet


It sounds contraindicative but prolonged use of laxatives actually results in constipation.

Excessive use of laxatives can result in “reflex constipation” as the bowel loses its ability to perform its natural function. Moreover, this constipation can cause individuals to increase the dosage of laxatives which only exacerbates these physical consequences.

Permanent impairment

Excessive use of laxatives can also result in permanent impairment of the digestive system.

This means that there is a chance of paralysis of the muscles used in digestion which can lead to the surgical removal of part or the entire colon and requires dependence of a colostomy bag.

Increased risk of cancer

Prolonged abuse of laxatives and damage to the colon increases an individual’s risk of colon cancer.

Laxative Withdrawal

The severity of laxative abuse is not an indicator of the severity of withdrawal. The best way to lessen effects of the withdrawal is to prepare in advance and develop a plan for coping. Common side effects are constipation, fluid retention, and temporary weight gain (Eating Disorders Review, 1999).

Just as any weight loss from using laxatives is temporary; it is important to remember that this weight gain is temporary and is mainly due to increased fluid retention. These symptoms can be especially difficult for an individual struggling with an eating disorder as they are highly reactive to weight gain and “feeling fat” (a statement often used to describe bloating, discomfort, and any unpleasant emotions). Withdrawal typically lasts anywhere from 1-3 weeks.
