Excessive laxative use can cause a range of health issues, including dehydration and electrolyte imbalance. People with eating disorders such as bulimia nervosa often misuse laxatives, incorrectly believing that they can support rapid weight loss. However, laxatives act on the large intestine, where most calories have already been absorbed.
Laxative misuse can lead to a loss of vital electrolytes such as potassium, sodium, and magnesium, which can cause a range of symptoms including neuromuscular dysfunction, gastrointestinal dysfunction, and an inability of the kidneys to concentrate urine.

What You'll Learn
Laxative abuse can lead to dehydration
Laxatives can induce bowel movements that contain liquids, minerals, electrolytes, and indigestible fibre. This can result in a lower number on the scale, but the "water weight" returns when the person rehydrates.
Laxative abuse can also lead to physical dependence, where the body relies on these agents for regular bowel movements. Over time, the colon may stop reacting to the usual laxative dose, requiring larger doses to produce bowel movements and exacerbating the cycle of misuse.
Treatment for laxative abuse
Treatment for laxative abuse involves a comprehensive approach, including stopping laxative use, psychological intervention, and supportive care. It is important to seek medical advice for laxative misuse.

Laxatives are ineffective for weight loss
Excessive laxative use can cause an electrolyte imbalance, as well as other health issues. It is a common misconception that laxatives can be used for weight loss. However, this is not only ineffective but also unsafe. Here's why:
Laxatives are intended to treat constipation by softening stool or stimulating bowel movements. While passing more stools may give the impression of weight loss, it is only temporary and not indicative of actual weight loss. The weight loss that occurs from taking laxatives is primarily due to water loss, not fat loss. This is because laxatives work by drawing water into the intestinal tract and stool, making it softer and easier to pass. This additional water is then eliminated from the body along with the stool, resulting in a temporary decrease on the scales. However, this is not a true reflection of body fat loss.
Stimulant laxatives, which encourage the movement of stool through the digestive tract, have only a modest effect on calorie absorption. Research suggests that the belief that laxatives prevent the body from absorbing calories is incorrect. In reality, the body absorbs calories, fat, and most nutrients before they reach the large intestine, where laxatives primarily act. Therefore, taking laxatives does not significantly impact weight loss or prevent weight gain.
Furthermore, laxative abuse can lead to serious health complications. It can cause dehydration, which may result in headaches, thirst, dry mouth, and in severe cases, heart problems, kidney failure, and even death. Additionally, frequent use of laxatives can irritate the gut lining, leading to a risk of bloody stools, and may contribute to long-term constipation. It is also important to note that laxative dependency can develop, where the gut becomes reliant on stimulation to move food along the intestinal tract. This can lead to difficulties in having bowel movements without the use of laxatives.
Laxatives are not a safe or effective method for weight loss. They do not reduce body fat or promote long-term weight loss. Instead, it is recommended to adopt sustainable lifestyle changes, such as eating a nutritious, balanced diet, increasing physical activity, and practicing self-care to improve body image. Reaching and maintaining a healthy weight is important, but it should be done in a safe and sustainable manner that promotes overall well-being.

Laxative misuse is a feature of the eating disorder bulimia nervosa
Excessive laxative use can cause a range of health issues, including fluid loss, dehydration, and electrolyte imbalances. The misuse of laxatives is a common feature of eating disorders, particularly in individuals with bulimia nervosa. The drive to control weight and the fear of gaining weight are often the reasons behind the misuse of laxatives. However, it is important to understand that laxatives are not an effective means of weight loss. The following paragraphs will delve into the specifics of how laxative misuse is a characteristic of bulimia nervosa.
Laxative misuse is prevalent among individuals with bulimia nervosa, with studies reporting that up to 75% of those with the disorder misuse laxatives. This misuse is a form of purging, where individuals attempt to induce diarrhoea to eliminate food and calories from their bodies, prevent weight gain, and achieve a feeling of emptiness. However, it is important to note that laxatives primarily target the large intestine, where most of the nutrients from food have already been absorbed. As a result, any observed weight loss is primarily due to water loss rather than calorie or fat loss.
The physical consequences of laxative abuse in bulimia nervosa can be severe. Dehydration is a common side effect, and it can lead to symptoms such as dizziness, weakness, confusion, and even death if left untreated. Additionally, laxatives impact the absorption of crucial electrolytes like sodium and potassium, leading to an electrolyte imbalance in the body. This imbalance can result in tachycardia (rapid heart rate), stiff and achy joints, and, in prolonged and severe cases, shock, cerebral edema (swelling in the brain), seizures, and coma.
The misuse of laxatives can also lead to "reflex constipation," where the bowel loses its ability to function naturally. This constipation may lead individuals to increase their dosage of laxatives, further exacerbating the physical consequences. Furthermore, excessive laxative use can result in permanent impairment of the digestive system, including paralysis of the muscles used in digestion, which may require surgical removal of part or the entire colon and dependence on a colostomy bag.
The psychological factors contributing to laxative misuse in bulimia nervosa are complex. Individuals with this disorder often experience increased distress and anxiety after binge eating. The fear of weight gain and the desire to feel empty can be so strong that individuals disregard the potential health consequences of their compensatory behaviours. Additionally, individuals with bulimia nervosa may develop a psychological and physiological dependence on laxatives, making it challenging for them to stop using them.
Treating laxative misuse in bulimia nervosa requires a comprehensive approach. It involves addressing the psychological dependency on laxatives and how it relates to the individual's eating disorder. This may include therapy, education on normal bowel function, and addressing the anxiety and distress associated with binge eating. Additionally, medical oversight is necessary to treat electrolyte disturbances and physical complications that may arise from laxative misuse.

Laxative misuse can lead to physical dependence
Laxatives are commonly misused by patients with eating disorders, particularly those with bulimia nervosa and the binge-purge subtype of anorexia nervosa. The misuse of laxatives is a form of purging, which is a method to remove food from the body to prevent weight gain or promote weight loss. Laxatives are also commonly misused by people with body dysmorphia.
Laxative abuse occurs when someone wants to use laxatives to lose weight. However, laxatives do not reduce body fat or promote long-term weight loss and have a minimal effect on a decrease in caloric intake. The weight loss that does occur is temporary and due to a decrease in "water weight". Despite this, laxatives are often used to induce diarrhea to feel thinner, lighter, or "empty".
Over time, the misuse of laxatives can lead to a variety of issues, including dependency on these medications. A patient who abuses laxatives can become both psychologically and physiologically dependent on them, which can cause unpleasant and uncomfortable symptoms when individuals stop using them. Laxative abuse is frequently considered an addiction-like behaviour.
Long-term laxative misuse can lead to physical dependence, where the body relies on these agents for regular bowel movements. Over time, the colon may stop reacting to the usual laxative dose, necessitating increasingly larger doses to produce bowel movements. This can exacerbate the cycle of misuse.
The treatment for laxative misuse is primarily psychological and targeted toward addressing a patient's psychological dependency on laxatives and how that relates to their eating disorder. Physical dependency can be addressed through appropriate medical oversight to treat the electrolyte disturbances and edema formation, often through the use of prescribed diuretics in the early stages.

Prolonged and excessive laxative use can cause lasting damage to internal organs
Prolonged and excessive laxative use can have severe and lasting effects on the body's internal organs. Laxatives are only intended for occasional use and can be unsafe when used in excess. The misuse of laxatives is often associated with eating disorders, with individuals taking them to induce weight loss. However, this is a harmful misconception as laxatives are ineffective for weight loss and can cause a range of serious health issues.
The colon, also known as the large intestine, is particularly vulnerable to the damaging effects of laxative abuse. Over time, excessive laxative use can cause the colon to become unresponsive to normal signals for bowel movements, resulting in chronic constipation. This condition is known as "lazy" or atonic colon, where the organ loses its natural muscle tone and nerve signalling, leading to slower digestive muscle contractions. The colon may also suffer physical trauma from the repeated and forceful expulsion of stool, increasing the risk of bacterial infections.
The misuse of laxatives can also lead to liver and kidney damage. The kidneys are especially susceptible to harm due to the fluid losses caused by laxatives, which can result in chronic kidney disease. The repeated bouts of hypokalemia (low potassium) that can arise from laxative abuse contribute to a condition called hypokalemic nephropathy, which may lead to irreversible kidney damage and the need for hemodialysis.
Additionally, laxative abuse can cause electrolyte imbalances, disrupting the levels of essential minerals like potassium, sodium, and calcium. These electrolytes are crucial for regulating vital bodily functions, including the heartbeat, blood pressure, muscle movements, and digestion. Over time, these imbalances can negatively affect the proper functioning of the kidneys and heart. In severe cases, electrolyte loss can lead to life-threatening complications such as coma, seizures, and sudden cardiac arrest.
Excessive laxative use can also increase the risk of colon cancer. Research indicates that the overuse of laxatives, including stimulant and osmotic varieties, doubles the likelihood of developing colon cancer. This heightened risk is attributed to the strain placed on the colon and the potential for physical trauma to the colon lining, which can create openings for bacterial infections.
