Laxative Abuse: Understanding The Dangers

Laxatives are a common over-the-counter medication used to treat constipation. While they can be effective, it is important to follow the recommended dosage, as exceeding it may lead to serious health complications or even death. Overdosing on laxatives can cause severe dehydration, abnormal electrolyte levels, kidney damage, and heart problems. The most common signs of a laxative overdose include nausea, vomiting, diarrhoea, abdominal cramping, and dehydration. It is crucial to seek immediate medical attention if an overdose is suspected, as the symptoms can worsen over time.

What are the signs of a laxative overdose?

The signs of a laxative overdose vary from person to person and depend on the type of laxative consumed. Some common symptoms include nausea, vomiting, and diarrhea. Abdominal cramping, dehydration, and bloody stools may also occur. Dehydration can cause symptoms such as extreme thirst, dry mouth and skin, reduced urine output, and headaches. In severe cases, a laxative overdose can lead to muscle weakness, dizziness, fainting, coma, or even death.

Specific types of laxatives may cause additional symptoms. For example, Cascara Sagrada and Senna may cause blood in stools, severe weakness, and collapse. Castor oil may irritate the gastrointestinal tract. Magnesium-based laxatives can lead to severe and watery diarrhea, reduced blood pressure, weak muscles, lethargy, and breathing difficulties. Methylcellulose and related products can cause intestinal obstruction or choking. Overdosing on mineral oil may result in aspiration pneumonia, reduced blood sugar, and low blood pressure. Sodium phosphate overdoses can cause weak muscles and collapse.

If you or someone you know is experiencing any of these symptoms after taking laxatives, seek immediate medical attention, even if the symptoms seem mild. Call your local emergency number or a poison control hotline for further instructions and guidance.

What to do if you've overdosed on laxatives?

Overdosing on laxatives can have dangerous, and even deadly, side effects. If you or someone you know has overdosed on laxatives, it is important to act quickly and seek medical help. Here is what you should do:

Call for Emergency Help:

If you suspect an overdose, contact your local emergency number, such as 911 in the United States. Alternatively, reach out to your local poison control center by calling the national toll-free Poison Help hotline: 1-800-222-1222. Both options are free, confidential, and provide expert guidance.

Recognize Symptoms:

Nausea, vomiting, abdominal cramping, and diarrhea are common symptoms of a laxative overdose. More severe symptoms may include dehydration, electrolyte imbalances, a drop in blood pressure, gastrointestinal irritation, and choking or intestinal blockage if the laxatives are not taken with enough fluids.

Gather Information:

Before calling emergency services, try to gather the following information:

• Person's age, weight, and current condition
• Name of the laxative product (including ingredients and strength, if known)
• Time the laxative was ingested
• Amount of the product swallowed
• Whether the medicine was prescribed to the person

Take the Container:

If possible, take the container of the laxative with you to the hospital or emergency room. This will help medical professionals identify the specific product and its ingredients.

Follow Medical Instructions:

Do not attempt to induce vomiting or take any action without guidance from poison control or a healthcare provider. They will provide specific instructions to manage the overdose and treat the symptoms.

Monitor Vital Signs and Treat Symptoms:

At the hospital, medical providers will monitor the person's vital signs, including temperature, pulse, breathing rate, heart function, and blood pressure. They may also perform blood and urine tests, provide breathing support or intravenous fluids, and administer medications to address specific symptoms.

Remember, seeking immediate medical attention is crucial in the event of a laxative overdose. Do not delay treatment and follow the instructions of medical professionals to ensure the best outcome.

Who is most at risk of a laxative overdose?

People who are most at risk of a laxative overdose include young children and people older than 55, as well as those who are already dehydrated, have kidney disease, bowel obstructions, or bowel inflammation. Additionally, those who are taking other medications that can affect kidney function, such as diuretics, drugs for high blood pressure, or pain relievers like aspirin, ibuprofen, and naproxen, are also at higher risk.

The risk of a laxative overdose is also elevated for individuals with eating disorders who misuse laxatives in the belief that they aid in weight loss or prevent weight gain. This misuse can lead to a cycle of dependency and increased tolerance, ultimately resulting in an overdose.

It is crucial to follow the recommended dosage on the label or as prescribed by a healthcare professional. An overdose can occur when an individual takes more than the normal or recommended amount, which can have dangerous and even deadly consequences.

Furthermore, those with impaired kidney function who take laxatives containing magnesium are at risk of serious electrolyte and heart rhythm disturbances.

Why do people take laxatives?

Laxatives are medications that stimulate bowel movements and loosen up stool to ease its passage. They are often used to treat constipation, a condition caused by infrequent, painful or difficult bowel movements. However, laxatives are also commonly misused as a method for weight loss. Many people believe that using laxatives can help increase the frequency of bowel movements and allow for quick and easy weight loss. This is not true, as laxatives do not lower calorie absorption and only lead to a temporary reduction in weight due to water loss.

There are several types of laxatives, including:

• Stimulant laxatives: These work by speeding up the movement of the digestive tract.
• Osmotic-type laxatives: This type causes the colon to retain more water, which increases bowel movement frequency.
• Bulk-forming laxatives: These move through the intestines undigested, absorbing water and adding bulk to the stool.
• Saline laxatives: Water is drawn into the small intestine to promote a bowel movement.
• Lubricant laxatives: This type of laxative coats the surface of the stool and the lining of the intestines to ease bowel movements.
• Stool softeners: These allow the stool to absorb more water, making it softer for easier passage.

Laxatives are available over the counter without a doctor's prescription, which has led to laxative abuse becoming common. Some people start taking laxatives to treat constipation and develop a laxative dependency due to long-term use. Others, particularly young women with eating disorders, abuse laxatives because they mistakenly believe that taking them will cause their bodies to absorb fewer calories. However, doctors say that laxatives are not a healthy or safe way to lose weight.

In addition to being ineffective for weight loss, laxative abuse can lead to dangerous side effects, including dehydration, electrolyte imbalance, gastrointestinal damage, liver damage, kidney failure, and even death.

What are the side effects of laxatives?

Laxatives are a category of medications used to address constipation and other gastrointestinal issues. They work by softening stools or stimulating the bowels to move, making it easier to pass stool. While laxatives are generally safe when used appropriately, they can have adverse side effects, and their overuse can lead to health complications.

Common side effects of laxatives include:

• Bloating and gas: Some laxatives can cause bloating and increased gas, which can be uncomfortable and embarrassing.
• Dehydration: Laxatives can lead to dehydration, especially if not taken with enough water. Dehydration may cause lightheadedness, headaches, and darker urine.
• Stomach cramps: Abdominal cramps and pain can occur as a side effect of taking laxatives.

Other potential side effects include:

• Electrolyte imbalance: Prolonged or excessive use of laxatives can disrupt the balance of water and salt in the body, leading to an electrolyte imbalance.
• Chronic constipation: Ironically, overuse of laxatives can worsen constipation by decreasing the colon's ability to contract and move stools.
• Intestinal obstruction: Large and dry stools can lead to a blockage in the intestines.
• Diarrhea: Diarrhea can result from overuse of laxatives, further increasing the risk of dehydration.
• Dependency: Prolonged use of laxatives can lead to a dependency, where the colon stops reacting to usual doses, requiring larger and larger doses.
• Internal organ damage: The colon can become stretched, and the muscle wall may become thin and flaccid due to overuse of laxatives.
• Increased risk of colorectal cancer: Non-fiber-based laxative use has been linked to an increased risk of colorectal cancer, although more research is needed.

It is important to follow the instructions on the medication to prevent or minimise these side effects. Taking laxatives for longer than directed or in larger doses than recommended can increase the risk of experiencing side effects. Additionally, some laxatives may interact with other medications, so it is important to consult a doctor or pharmacist before taking them if you are on any prescription drugs.
