Stimulant laxatives are the most common type of laxatives that are abused by patients with eating disorders. While laxatives are typically used for short periods, long-term use or overuse can lead to laxative withdrawal symptoms, which are temporary and usually mild. However, abrupt cessation of high-dose stimulant laxatives can cause severe edema, with one case study reporting a duration of 3 months. This is due to fluid retention and shifts in sodium and free water levels, resulting in rapid weight gain. Treatment for edema caused by laxative abuse involves the use of diuretics, with furosemide being the mainstay treatment.

Laxative withdrawal symptoms
While short-term laxative use is generally considered safe for most adults, long-term use or overuse can lead to physical dependence and withdrawal symptoms when stopped. Withdrawal symptoms are usually temporary and mild, but they can be uncomfortable and may require medical intervention. Here are some of the possible laxative withdrawal symptoms:
- Constipation and Bloating: One of the most common withdrawal symptoms is worsening constipation, as the body adjusts back to normal bowel function. This can be accompanied by bloating and abdominal pain.
- Water Retention and Weight Gain: Temporary water retention is common during laxative withdrawal, which can lead to modest weight gain. However, this weight gain is due to fluid retention and not an increase in body fat.
- Gastrointestinal Issues: In addition to constipation, other gastrointestinal difficulties may arise, such as bowel obstruction and kidney damage.
- Electrolyte Imbalances: Overuse of laxatives can lead to electrolyte imbalances, causing symptoms such as muscle cramps, weakness, irregular heartbeats, and in severe cases, arrhythmias or seizures.
- Dehydration: As laxatives increase fluid expulsion, dehydration is a common side effect of overuse. This can result in symptoms like thirst, dry skin, and fatigue.
- Psychological Distress: Laxative abuse is often linked to eating disorders and other psychological issues. Withdrawal can bring about feelings of anxiety and distress, and it is important to address the mental health aspects of abuse during recovery.
The treatment for laxative withdrawal focuses on managing these symptoms and restoring the body's fluid and electrolyte balance. In some cases, medical supervision and detoxification may be necessary. Psychological support, such as cognitive-behavioral therapy (CBT) or dialectical behavior therapy (DBT), is also an important part of the recovery process.

Edema treatment
Edema is the medical term for swelling. It can affect a small area or the entire body. Edema happens when small blood vessels leak fluid into nearby tissues, which then builds up and causes the tissue to swell. This can happen almost anywhere in the body. Peripheral edema, for example, usually affects the legs, feet, and ankles but can also occur in the arms. Pedal edema happens in the feet and lower legs, and lymphedema is swelling in the arms and legs, often caused by damage to the lymph nodes.
There are several types of edema, including:
- Peripheral edema: Affects the legs, feet, and ankles, but can also occur in the arms. It could indicate issues with the circulatory system, lymph nodes, or kidneys.
- Pedal edema: Occurs when fluid gathers in the feet and lower legs, more common in older individuals or during pregnancy.
- Lymphedema: Swelling in the arms and legs caused by damage to the lymph nodes, often due to cancer treatments or the cancer itself.
- Pulmonary edema: Fluid collects in the air sacs of the lungs, making breathing difficult, particularly when lying down. It can cause a fast heartbeat, a feeling of suffocation, and coughing up foamy spittle, sometimes with blood.
- Cerebral edema: A serious condition where fluid builds up in the brain, possibly due to head trauma, blood vessel blockage, tumors, or allergic reactions.
- Macular edema: Fluid builds up in the macula, a part of the retina in the eye, due to damaged blood vessels leaking fluid.
There are various causes of edema, including:
- Injuries or inflammation: For example, a twisted ankle, bee sting, or skin infection.
- Allergic reactions: Nearby blood vessels leak fluid into the affected area as part of an allergic response.
- Obstruction of fluid flow: Blockage of drainage can cause fluid backup, such as a blood clot in the deep veins of the leg or a tumor blocking blood or lymph flow.
- Critical illness: Burns, severe infections, or other critical illnesses can cause a reaction leading to fluid leakage into tissues.
- Congestive heart failure: Weakened heart function leads to fluid buildup, resulting in leg edema and possibly fluid in the lungs or abdomen.
- Liver disease: Severe cases like cirrhosis cause fluid retention and low levels of albumin and other proteins in the blood, leading to fluid leakage into the abdomen and leg edema.
- Kidney disease: Nephrotic syndrome can cause severe leg edema and, in some cases, whole-body edema.
- Pregnancy: Mild leg edema is common during pregnancy, but complications like deep vein thrombosis and preeclampsia can also cause edema.
- Medications: Certain drugs, such as NSAIDs (ibuprofen, naproxen), calcium channel blockers, corticosteroids, and pioglitazone, can lead to mild leg edema.
To effectively treat edema, addressing the underlying cause is crucial. This may involve:
- Allergy medications: Treating swelling caused by allergies.
- Improving fluid drainage: In cases of blocked drainage, restoring normal drainage can help, such as using blood thinners to break down blood clots.
- Tumor treatment: Tumors blocking blood or lymph flow may be shrunk or removed through surgery, chemotherapy, or radiation.
- Diuretics: For leg edema related to congestive heart failure or liver disease, diuretics like furosemide can be prescribed to increase urination and reduce fluid retention in the legs.
- Sodium restriction: Limiting sodium intake can help manage edema by reducing fluid retention.
In the context of laxative abuse cessation leading to edema, the treatment approach is centred around diuretic use, particularly furosemide, to address the significant fluid overload.

Weight gain after laxative abuse
Laxatives are medicines to relieve constipation and are recommended by doctors only when lifestyle changes like eating more fibre, exercising, and drinking more water do not help. However, some people use laxatives to lose weight, which is dangerous and can lead to sickness. This is because laxatives target the large intestine, which is where food goes after nutrients have already been absorbed by the body. Therefore, any weight loss from laxatives is solely from water loss, and the weight will be gained back as soon as the person drinks something.
Despite this, people with eating disorders may use laxatives to lose weight. The most common consequence of laxative abuse is dehydration, which can lead to dizziness, weakness, confusion, and even death in extreme cases. Laxatives can also cause an electrolyte imbalance, which can lead to a rapid heart rate, stiff and achy joints, and, in prolonged and severe cases, shock, cerebral edema, seizures, and coma.
In addition, laxatives can cause constipation and damage to the intestines, increasing the risk of colon cancer. They can also interfere with the absorption of prescription medications and cause rectal bleeding.
Abrupt cessation of high-dose laxatives can lead to edema and rapid weight gain due to fluid shifts and electrolyte disturbances. A case study reported a 30-year-old female with a history of constipation and chronic laxative use who presented with peripheral edema and an 8.62 kg (19-lb) weight gain after stopping her laxative use. Her edema and weight gain were treated with furosemide, and she returned to her baseline weight after one week.
It is important to note that any weight gain after discontinuing laxative abuse is temporary and due to increased fluid retention. This can be especially challenging for individuals with eating disorders who are highly sensitive to weight gain. The withdrawal period typically lasts from one to three weeks. Seeking help from a treatment team, including a physician, therapist, and registered dietitian, is crucial to managing the medical complications and psychological aspects of laxative abuse and eating disorders.

Side effects of laxative overuse
Laxatives are medicines used to treat constipation by softening stools or stimulating the lower intestine to push out stool. They are available over the counter and are easy to obtain. However, laxatives can have serious side effects when overused or abused.
Laxative abuse occurs when individuals use laxatives to achieve their ideal body weight or shape. This is driven by a false belief that laxatives can quickly move food through the body and clear out calories before they are absorbed. Despite this, laxatives primarily act on the large intestine, where most nutrients and calories have already been absorbed by the small intestine. As such, the weight loss achieved is only temporary and due to the loss of "water weight".
Overuse of laxatives can lead to a range of side effects and long-term health consequences. One of the most common side effects is dehydration, as laxatives remove water from the body. Dehydration can cause symptoms such as thirst, decreased urination, headaches, light-headedness, dry mouth, weakness, and fatigue. It can also lead to more severe complications, including kidney damage and even death if left untreated.
Another serious side effect of laxative overuse is electrolyte disturbances, including abnormalities in sodium, potassium, and chloride levels. These electrolytes are lost at abnormally high rates in diarrhoea, which can lead to weakness, irregular heartbeats, and sudden death. Additionally, laxative abuse can cause mineral deficiencies, such as disturbances in magnesium, sodium, potassium, and phosphate levels, impairing muscle function.
Laxative abuse can also result in gastrointestinal damage and impaired intestinal function. It can damage the nerves and muscles of the colon, leading to a condition known as a "'lazy colon' or irritable bowel syndrome. This damage can cause chronic constipation, making it difficult to have normal bowel movements without the use of laxatives. In some cases, laxative abuse may increase the risk of colon cancer.
Furthermore, laxative overuse can have psychological impacts, contributing to or exacerbating existing mental health issues. Individuals may experience depression, anxiety, shame, and social isolation due to the unpredictable nature of bowel movements and the embarrassing side effects of laxative abuse, such as gas and diarrhoea.
Other potential side effects of laxative overuse include urinary tract infections (UTIs), intestinal paralysis, rectal bleeding, abdominal cramping, and muscle spasms and cramps. Abrupt cessation of high-dose laxatives can also lead to severe edema and rapid weight gain due to fluid shifts and electrolyte disturbances.
It is important to seek medical help if you or someone you know is struggling with laxative abuse. Treatment for laxative abuse involves rehydration, stabilisation of electrolytes and minerals, and psychological support to address the underlying causes and develop healthy coping mechanisms.

Treatment for laxative overuse
The first step in treating laxative overuse is to determine what may be promoting the behaviour, such as an eating disorder or misinformation about what constitutes a healthy bowel habit. The next step is to stop the use of stimulant laxatives and replace them with fibre or osmotic supplements to establish normal bowel movements. Education and further treatment may be required to maintain a healthy bowel program. In the case of an eating disorder, referral for psychiatric treatment is essential to lessen the reliance on laxatives as a method to alter weight and shape.
Individuals who have abused laxatives may need to be rehydrated and have their body electrolytes and minerals stabilised. This process should be carefully monitored by medical professionals with expertise in eating disorders. Support from healthcare providers, therapists, and family is also important, as people who have abused laxatives may feel the urge to start using them again. Developing healthy coping skills, self-confidence, and self-acceptance as part of a comprehensive eating disorder treatment program is important in helping people embrace their bodies and resist relapsing.
As individuals return to more normal eating, dietitians can help with eating plans that prevent constipation. It is important to drink plenty of fluids, slowly increase fibre in the diet through eating fruits, vegetables, whole grain breads, and whole grain cereals, and to exercise regularly. All of these steps can get the intestines working and help keep you "regular".
