Laxatives And Anorexia: A Dangerous Combination

Anorexia is an eating disorder characterised by an abnormally low body weight and an intense fear of gaining weight. Those with anorexia often have a distorted view of their bodies, believing themselves to be overweight even when they are dangerously underweight. Some people with anorexia use laxatives as a form of purging to control their weight. Laxatives are medicines that treat constipation by softening stools or stimulating the lower intestines to push out stools more easily. However, laxatives do not aid weight loss. By the time they act on the large intestine, most food and calories have already been absorbed by the small intestine. Despite this, laxatives are frequently misused by those with eating disorders, including anorexia, to eliminate unwanted calories and lose weight. This can have severe health consequences, including dehydration, disturbance of electrolyte and mineral balances, laxative dependency, and internal organ damage.

Laxatives don't aid weight loss

Laxatives are medicines for constipation and are not meant to be used for weight loss. They do not aid weight loss because, by the time they act on the large intestine, most foods and calories have already been absorbed by the small intestine. Laxatives artificially stimulate the large intestine to empty its contents, but the weight lost is mostly water weight, which returns as soon as the individual rehydrates.

Laxatives are designed to relieve constipation by softening the stool or stimulating bowel movements. People may assume that passing more stools will lead to weight loss. However, although people may feel “lighter” temporarily, there is no evidence to support the use of laxatives as a safe or effective weight loss method.

The temporary weight loss that people may experience from taking laxatives is due to water loss, not fat loss. Losing water is not the same as losing body fat. Many laxatives work by helping the gut absorb more water from the body or keeping water in the gut around the stool. This water softens the stool, making it easier to pass. It may also cause diarrhea, which is very watery stool. As this additional water passes out with the stool, a person may weigh less after using laxatives. However, this effect is only temporary.

Laxatives do not reduce body fat or promote long-term weight loss. Even at high doses, stimulant laxatives, which encourage the movement of stool through the digestive tract, have only a “modest effect” on calorie absorption.

Using laxatives for weight loss is not only ineffective but also dangerous and can lead to various health complications, including dehydration, electrolyte imbalance, intestinal damage, and increased risk of colon cancer. It can also contribute to the development of an eating disorder.

Laxatives cause dehydration

Laxatives are intended to be used as a short-term solution to constipation. However, their misuse as a weight-loss tool is prevalent, especially among individuals with eating disorders. This is a dangerous practice with severe health consequences, including dehydration.

Laxatives do not aid weight loss. By the time they act on the large intestine, most foods and calories have already been absorbed by the small intestine. Instead, laxatives cause the loss of water, minerals, and electrolytes from the colon. This loss of essential fluids results in dehydration, which further taxes the organs and can ultimately lead to death.

Dehydration caused by laxative abuse can lead to tremors, fainting, weakness, and blurred vision. It puts stress on the organs, requiring medical treatment. If an individual chronically misusing laxatives refuses to rehydrate, they risk severe dehydration, which can cause organ damage and even death.

The body compensates for dehydration by retaining water, which results in bloating. This can trigger individuals to continue misusing laxatives, creating a vicious cycle. The overuse of laxatives can lead to a dependency on higher and higher doses, further exacerbating the problem.

It is important to understand that laxatives do not help with weight loss and that their misuse can have severe health consequences, including dehydration. Seeking medical help and support from healthcare providers, therapists, and family is crucial to break the cycle of laxative abuse and restore a balance of essential nutrients and normal functioning.

Laxatives can lead to constipation

Laxatives are often misused by individuals with eating disorders, such as anorexia nervosa, in an attempt to lose weight, "feel thin", or "feel empty". However, this practice can lead to a range of serious health complications, including constipation.

Laxatives are designed to relieve constipation by increasing stool motility, bulk, and frequency, stimulating the large intestine to empty its contents. While this can be effective for occasional constipation, the misuse or overuse of laxatives can lead to adverse effects, including chronic constipation. This is because the stimulant laxatives may weaken the body's natural ability to defecate, leading to a dependency on the laxatives for bowel movements. Over time, the colon may stop reacting to the usual doses, requiring larger and larger amounts to produce any effect. This can result in a vicious cycle, with the individual becoming increasingly constipated despite their continued or increased use of laxatives.

The risk of constipation is further heightened by the dehydration caused by laxative misuse. Laxatives cause the body to lose water, minerals, and electrolytes, which are necessary for proper nerve and muscle function. Dehydration can lead to tremors, weakness, blurry vision, fainting, and kidney damage. If fluids are not replaced, it can even result in death.

Additionally, the misuse of laxatives can cause internal organ damage, including a stretched or "lazy" colon, colon infection, and irritable bowel syndrome (IBS). The disruption of electrolyte and mineral balances can also affect vital organs such as the heart and colon, leading to further complications.

To prevent constipation and other health issues, it is crucial to use laxatives sparingly and only as directed by a healthcare professional. A healthy diet rich in fiber, regular exercise, and adequate fluid intake can also help prevent constipation. Seeking support from health professionals, support groups, friends, and family is essential for individuals struggling with laxative misuse and eating disorders.

Laxatives can cause organ damage

Anorexia nervosa is an eating disorder characterised by cycles of binging and purging. Those with anorexia often misuse laxatives as a way to induce bowel movements, believing that they can prevent the absorption of calories and nutrients. However, this is a myth, as food is digested in the small intestine, and by the time it reaches the large intestine, most nutrients have already been absorbed. As a result, the weight loss caused by laxatives is only due to the loss of water, minerals, and electrolytes.

Laxative misuse can lead to severe health complications, including organ damage. The loss of vital electrolytes such as sodium, potassium, magnesium, and phosphorus can disrupt the normal functioning of the body's organs. Electrolytes are essential for the proper functioning of nerves and muscles, including those of the colon and heart. This disruption can lead to improper functioning of vital organs, including the heart.

Prolonged and excessive laxative use can also cause physical trauma to the colon lining, increasing the risk of bacterial infections. The colon may become stretched, and the muscle wall may become thin and flaccid, leading to a condition known as "lazy" or atonic colon. This can result in chronic constipation, even after stopping laxative use. In rare cases, chronic laxative misuse can lead to liver and kidney damage.

The misuse of laxatives can also increase the risk of colon cancer. The forceful expulsion of stool can cause physical trauma to the colon, and the increased gut motility can lead to organ damage and loss of function. The disruption of the natural muscle tone of the colon can have long-term effects, and the colon may stop reacting to normal signals for bowel movements.

Laxative misuse is a dangerous practice that can have severe consequences for the body's organs and overall health. It is important to seek medical advice and treatment for laxative misuse, which often involves a comprehensive approach including medical, psychological, and supportive measures.

Laxatives are used for self-punishment

Anorexics may use laxatives as a form of self-punishment. While weight loss may appear to be the goal of laxative abuse, researchers have found that self-punishment is often a driving factor. Laxative abuse is one of the more physically self-abusive forms of purging, and individuals with anorexia may choose it for its self-harming aspect.

The psychology behind this may involve a desire to decrease the fear of weight gain and simultaneously allow the individual to focus on the pain and consequences of the abuse instead of their weight. The individual may also seek to achieve a sense of emotional emptiness or "purification" through the "emptying" that laxatives provide.

The use of laxatives for self-punishment can lead to a downward spiral into depression. As laxative abuse depletes the body of electrolytes, it can cause changes in brain functioning and mood, leading to feelings of depression and helplessness. The struggle with addiction and the inability to change behaviour can further contribute to negative emotions and self-perception.

Laxative abuse can also result in physical harm and severe health consequences. Despite the belief that laxatives can help eliminate unwanted calories and promote weight loss, they primarily act on the large intestine, where most food and calories have already been absorbed by the small intestine. Instead, laxatives cause the loss of water, minerals, electrolytes, and indigestible fibre and wastes from the colon. This can lead to dehydration, disturbance of electrolyte and mineral balances, laxative dependency, internal organ damage, and an increased risk of colon cancer.
