With over two-thirds of Americans classified as overweight or obese, the market for weight-loss solutions is booming. Supplement companies are keen to capitalize on this demand, offering a variety of products that promise quick and easy weight loss. However, it's crucial to understand the potential risks and side effects associated with these products. The supplement market is lightly regulated, allowing for the inclusion of hazardous substances, chemical variations of banned substances, and dosages exceeding safe limits in over-the-counter (OTC) weight-loss supplements.
Understanding Weight Loss Medications and Supplements
Diet pills, including prescription drugs and over-the-counter supplements, often work by suppressing appetite or reducing the body's ability to absorb nutrients. These products are frequently marketed with claims of burning fat, eliminating sugar cravings, boosting metabolism, improving mood, increasing energy, and promoting lean muscle mass. However, the Food and Drug Administration (FDA) does not regulate over-the-counter diet pills and supplements, making it essential to exercise caution when considering these options.
Misuse of Diet Pills
Irresponsible use of diet pills and supplements can have serious health consequences. Misuse includes:
- Combining multiple diet pills at once.
- Taking prescription weight loss drugs without medical supervision.
- Exceeding the recommended daily dose of a dietary supplement.
- Combining diet pills with diuretics and/or laxatives.
- Combining diet supplements with illegal stimulants.
The Link Between Diet Pills and Eating Disorders
The promotion of weight loss supplements can contribute to disordered eating behaviors, capitalizing on individuals' desperation or insecurity. A study in the American Journal of Public Health found that those who used diet pills or laxatives for weight manipulation had a higher risk of being diagnosed with an eating disorder within three years. Diet pill abuse can also be a symptom of eating disorders, used as a form of purging to compensate for calories consumed.
Diet Culture and Misinformation
Social media often features sponsored posts from celebrities promoting weight loss supplements, creating the impression that these products are safe and effective. However, this information is often misleading, with celebrities potentially unaware of the products' ingredients or effects. The ready availability of these pills in stores and pharmacies further reinforces the false perception of safety.

Specific Ingredients and Their Side Effects
Several ingredients commonly found in weight loss pills have been associated with adverse effects:
- Sibutramine: This controlled substance was removed from the market due to its potential to substantially increase blood pressure and heart rate, posing a significant risk for individuals with a history of cardiovascular issues.
- 1,3-dimethylamylamine (DMAA): A banned substance linked to serious health risks, including heart problems.
- Ephedra: This stimulant was banned due to severe side effects such as heart attack, stroke, and seizures.
- DNP (Dinitrophenol): Overdose can cause itchy, inflamed skin, and rapid cataract development.
Prescription Weight Loss Medications
While over-the-counter supplements carry risks, prescription weight loss medications also have potential side effects that should be carefully considered.
Common Prescription Weight Loss Drugs and Their Side Effects:
- Phentermine: Side effects include headache, overstimulation, high blood pressure, insomnia, rapid or irregular heart rate, and tremor.
- Phentermine-Topiramate (Qsymia): Side effects include abnormal sensations, dizziness, altered taste, insomnia, constipation, and dry mouth. This combination cannot be taken during pregnancy.
- Naltrexone-Bupropion (Contrave): Common side effects include nausea, constipation, headache, vomiting, dizziness, insomnia, dry mouth, and diarrhea.
- Liraglutide (Saxenda): Gastrointestinal issues are the most common complaint.
- Semaglutide (Wegovy): Gastrointestinal issues are common, and headlines have warned of increased suicidal ideation.
- Orlistat (Alli, Xenical): Side effects can include oily spotting, gas, stomach pain, fecal urgency or incontinence, soft stools, and the possibility of serious liver injury.
- Tirzepatide (Zepbound): Common side effects include constipation, upset stomach, bloating, and diarrhea. Potential serious side effects also include stomach problems, kidney problems or failure, gallbladder problems, pancreatitis, or hypoglycemia.
Newer Weight Loss Medications
Newer prescription weight loss drugs like Wegovy or Zepbound can produce significant weight loss results, but often come with stomach-related side effects like nausea, vomiting, diarrhea, or stomach-area pain.
Important Considerations for Prescription Weight Loss Drugs
- Eligibility for weight loss medications is typically based on body mass index (BMI).
- Many medications have gastrointestinal side effects, which can be managed with dietary adjustments and careful monitoring.
- Stopping these medications can lead to weight regain.
- Some weight loss drugs may interact with other medications.
- Increased blood pressure and heart rate, insomnia, nervousness, restlessness, dependence, abuse or withdrawal may occur with long-term use.

Managing Gastrointestinal Side Effects of Weight Loss Medications
Nearly half of the people who take a GLP-1 weight management medication experience one or more gastrointestinal side effects. The most commonly reported ones are nausea and vomiting, acid reflux, bloating, stomach cramps, diarrhea and/or constipation. While these symptoms are generally mild and temporary, they may make it difficult to stick with the treatment.
Tips for Minimizing Gastrointestinal Side Effects:
- Think about your food choices. Limit high fat and greasy foods that take longer to digest. Limit concentrated sweet foods and sugary beverages. Limit spicy foods. Include high fiber foods. Stay hydrated.
- Re-think portion sizes. Start out by serving yourself and eating smaller portions. Eat on smaller plates and bowls.
- Listen to your body. Get in touch with your bodyâs signs of fullness and stop eating at the first sign of fullness.
- Prioritize adequate nutrition. Consume healthy nutrients to preserve muscle mass and lean body mass. A protein drink can help provide your body with nutrients without making you feel nauseous.
Seeking Support for Medication Misuse and Disordered Eating
If you're concerned about your use of diet pills or supplements, talking to a healthcare professional is a crucial first step. A healthcare professional can help you understand the reasons for negative views of your body shape and/or weight and develop a plan to feel more positive about your body. They can also evaluate whether diet pill use has resulted in health complications or is a symptom of a larger issue, such as an eating disorder.
