The pursuit of effective weight loss solutions has led to a surge in the popularity of various medications and supplements. This article explores the ingredients and considerations surrounding weight loss pills, including prescription drugs, over-the-counter supplements, and the importance of consulting healthcare professionals.
The Rise of Weight Loss Medications
In recent years, drugs like Ozempic, Wegovy, and Zepbound have gained significant attention for their weight loss effects. Ozempic, initially intended for treating diabetes, was quickly adopted for weight loss purposes. Wegovy, a higher-dose version of semaglutide, is officially marketed as an obesity treatment. Zepbound, another recent addition, has also shown promising results. The active ingredient in Ozempic, semaglutide, has demonstrated effectiveness for weight loss in research settings.
These medications mimic a hormone called glucagon-like peptide-1 (GLP-1), which curbs hunger. GLP-1 slows down the movement of food from the stomach to the small intestine, increasing insulin production and lowering blood sugar. This results in reduced appetite and subsequent weight loss. Clinical trials have shown that obese patients can lose a significant percentage of their body weight using these drugs.
Oral Semaglutide: A Pill-Based Option
Novo Nordisk presented findings on an oral version of semaglutide for weight loss in individuals who are obese or overweight but do not have Type 2 diabetes. Participants in the phase 3 clinical trial lost an average of 15% of their body weight after 68 weeks. This weight loss was comparable to that achieved with weekly injections of semaglutide.
An oral weight loss drug may be a more appealing option for some people, as many are accustomed to taking tablets. However, oral semaglutide has specific requirements: it must be taken daily, in the morning, on an empty stomach.

Orforglipron: Another Oral Weight Loss Drug
Eli Lilly presented results on an oral weight loss drug called orforglipron. Participants taking orforglipron lost an average of 9.4% to 14.7% of their body weight after 36 weeks, depending on the dose. Like oral semaglutide, orforglipron is taken daily in the morning.
Concerns and Side Effects
While these drugs offer promising results, they also come with potential side effects. Common side effects include nausea, vomiting, fatigue, diarrhea, and constipation. Some patients may experience more severe side effects, such as dehydration and exacerbation of atrial fibrillation.
GLP-1 agonists can slow digestion, leading to conditions like stomach paralysis and bowel obstructions. There have been reports of patients requiring emergency care due to severe gastrointestinal issues.
The History of Weight Loss Medications
The history of weight loss medication is filled with drugs that initially seemed like impressive, easy solutions. Fen-phen, a combination of fenfluramine and phentermine, was a popular diet drug in the 1990s but was later linked to vascular and cardiac issues. Amphetamines were also once widely prescribed for weight loss until they were associated with high blood pressure, heart complications, anxiety, and aggression.
The Role of Supplements
The demand for weight loss solutions has also led to a proliferation of supplements. However, supplements are not subject to the same rigorous testing and approval processes as prescription drugs. The Dietary Supplement Health and Education Act of 1994 created a regulatory framework that largely bypasses the FDA, meaning the FDA cannot require rigorous pre-screening for safety and effectiveness.

Some supplements marketed for weight loss have been found to be adulterated, sometimes containing extreme levels of stimulants. It is essential to be cautious when considering weight loss supplements and to consult with a healthcare professional before taking them.
Specific Ingredients of Concern
Several ingredients found in weight loss products have raised concerns:
- Sibutramine: A controlled substance that was removed from the market in October 2010 for safety reasons. It can substantially increase blood pressure and/or heart rate and may present a significant risk for people with a history of coronary artery disease, congestive heart failure, arrhythmias, or stroke.
- Desmethylsibutramine: A substance structurally similar to sibutramine, posing similar health risks.
- Phenolphthalein: A chemical that is not an active ingredient in any approved drug in the United States.
The FDA has issued warnings against products containing these ingredients, advising consumers not to purchase or use them.
Qsymia: A Prescription Weight Loss Medication
Qsymia is a prescription medication used to help people with obesity or those who are overweight with medical problems lose weight. It contains two medicines called phentermine and topiramate, which may work together to reduce appetite.
Common side effects of Qsymia include numbness, tingling, dizziness, loss of taste, trouble sleeping, constipation, and dry mouth. Serious side effects can include suicidal thoughts and actions, mood changes, concentration problems, eye problems, metabolic acidosis, kidney problems, and severe skin reactions.

Qsymia should not be used by people who are allergic to any of its ingredients, those with glaucoma or overactive thyroid, or women who are pregnant. It can interact with other medications, including those that cause dizziness and sleepiness, MAOIs, birth control pills, and diuretics.
Ozempic: A Closer Look
Ozempic (semaglutide) is a prescription medication used for adults with type 2 diabetes to lower their blood sugar levels. It mimics a natural hormone called GLP-1, which is released when we eat to help balance blood sugar and make us feel full after meals. While Ozempic is not FDA-approved for weight loss, it can help with weight loss and weight loss maintenance when used with diet and exercise.
Common side effects of Ozempic include stomach problems like nausea, vomiting, diarrhea, stomach pain, and constipation. More serious side effects can include thyroid tumors, severe gastrointestinal adverse reactions, acute pancreatitis, and kidney injury.
The Importance of a Holistic Approach
While weight loss medications and supplements can play a role in weight management, they are not a substitute for a healthy lifestyle. A holistic approach to weight loss includes:
- Balanced Diet: Prioritizing fruits, vegetables, whole grains, lean protein, and healthy fats.
- Regular Exercise: Engaging in physical activity to improve cardiovascular health, strengthen bones, and boost mood.
- Lifestyle Changes: Addressing social, environmental, and genetic factors that contribute to excess weight.
- Medical Supervision: Consulting with a physician or nutritionist to monitor progress and flag unhealthy behaviors.
The Future of Weight Loss Treatments
Pharmaceutical companies are continuously working to develop better drugs for weight loss. Additional GLP-1s might enter the market in a few years. Legislative efforts are underway to expand insurance coverage for GLP-1 medications. As research progresses, the cost of these medications is expected to decrease, making them more accessible to those who need them.
