Diet pills, also known as appetite suppressants, are a type of weight-loss medication for people with obesity (a body mass index or BMI over 30). While there is no explicit age limit on diet pills, they are generally limited for teens due to the lack of research on the effects of weight-loss medications on adolescents. The U.S. Food and Drug Administration (FDA) has approved certain weight management medications for children ages 12 and older, such as orlistat (Xenical) and liraglutide (Saxenda). However, experts recommend that weight-loss medications should only be considered for teens after they have tried a weight management program and met certain criteria, including a BMI of at least the 95th percentile.

What You'll Learn
Weight loss drugs for teens
There are several weight loss drugs that have been approved for use in teens. One of the most widely prescribed is Wegovy, which is a brand name for semaglutide, a GLP-1 receptor agonist. It works by moderating blood glucose levels and creating a sense of fullness. Other drugs in the same class as Wegovy include Ozempic and Tirzepatide (Zepbound). Liraglutide (Saxenda) is another injectable medication that works similarly to Wegovy and has been approved for use in teens. Orlistat is a weight loss drug that has been available for many years and is approved for teens 12 and older. It works by blocking the absorption of fat, causing it to exit the body through waste. A medication combining phentermine and topiramate has also been approved for teens 16 years and older. This medication acts as an appetite suppressant, reducing hunger and cravings.
While these drugs can be effective in treating obesity in teens, there are concerns about their long-term effects, especially when used in adolescents who are still physically and mentally developing. Additionally, the drugs can be expensive and may not always be covered by insurance. Some experts worry that the inclusion of weight loss drugs in the treatment of childhood obesity may be harmful, especially for those struggling with eating disorders. Side effects of these drugs can include nausea, vomiting, dizziness, abdominal pain, and diarrhoea.
It is important for teens and their parents to be well-informed about the potential benefits and risks of weight loss drugs. While these medications can be a useful tool, they should be used under the supervision of a healthcare provider and combined with healthy lifestyle changes.

Side effects of diet pills
Diet pills, or weight-loss medications, can have several side effects, and it is important to familiarize yourself with these before taking them. The side effects vary depending on the type of diet pill, and some pills have more severe side effects than others. For example, Orlistat, a lipase inhibitor, can cause an oily discharge from the rectum, flatus with discharge, increased defecation, and fecal incontinence. On the other hand, GLP-1 receptor agonists, such as liraglutide and semaglutide, can cause gastrointestinal issues such as nausea, vomiting, acid reflux, bloating, stomach cramps, diarrhoea, and constipation. Nearly half of the people who take a GLP-1 weight management medication experience one or more of these side effects. Tirzepatide, initially approved to treat type 2 diabetes, may cause thyroid tumours or thyroid cancer, so patients should be monitored for symptoms such as swelling in the neck, hoarseness, and trouble swallowing. Other potential side effects of weight-loss medications include gallbladder disease, an increased risk of fracture, and pancreatitis.
It is worth noting that side effects may resolve initially but could occur again with a dose increase. Symptoms typically decrease as the body adapts to the medication and eating habits change. To help manage the side effects of diet pills, it is recommended to make dietary changes such as limiting high-fat and greasy foods, sugary foods and beverages, and spicy foods. Eating smaller portions and prioritising adequate nutrition, such as consuming high-fibre foods and protein drinks, can also help reduce side effects.
Some diet pills, such as phentermine-topiramate and GLP-1 receptor agonists, are controlled substances and have the potential for addiction. These pills can cause rapid or irregular heartbeat, mood changes such as depression or anxiety, and cognitive changes like agitation, delirium, or psychosis. It is important to discuss side effects with a healthcare provider before starting any medication and to be aware of the eligibility requirements, which are typically based on body mass index (BMI).
While diet pills can be effective in reducing weight, they may not be suitable for everyone due to the potential side effects. It is important to consult a healthcare professional to determine the best course of treatment for weight loss, considering individual needs and health conditions.

Diet pills vs. weight loss surgery
While there is no explicit mention of an age limit for diet pills, sources indicate that minors as young as 12 years old have been prescribed weight loss drugs. However, it is important to note that the decision to prescribe weight loss medication to minors should be made by a licensed healthcare provider.
Now, when it comes to diet pills vs. weight loss surgery, there are several factors to consider. Both options are effective in promoting weight loss, but they differ in various ways.
Diet pills, also known as weight-loss medications or anti-obesity medications (AOMs), are typically taken orally and work by suppressing appetite, reducing cravings, and increasing the feeling of fullness. They can be prescribed by a healthcare provider for short-term or long-term use, depending on the specific medication and the patient's needs. Common prescription diet pills include Liraglutide (Saxenda®), Semaglutide (Wegovy®), Naltrexone-bupropion (Contrave®), and Phentermine-topiramate (Qsymia®). Diet pills are often recommended for individuals with a body mass index (BMI) between 27 and 35, especially those with obesity-related co-existing conditions. While diet pills can be effective, they may cause side effects such as nausea, constipation, abnormal sensations, dizziness, altered taste, insomnia, and dry mouth. Additionally, diet pills often require long-term or lifelong use to maintain results, and their effectiveness may decrease over time. Stopping the medication can lead to rapid weight regain.
On the other hand, weight loss surgery, also known as bariatric surgery, is a more invasive option that offers significant and sustained weight loss. It is generally recommended for individuals with a BMI greater than 35 who need substantial and rapid weight loss. The two most common types of weight loss surgery are sleeve gastrectomy and Roux-en-Y gastric bypass. While sleeve gastrectomy is not reversible, Roux-en-Y gastric bypass is partially reversible. Weight loss surgery leads to more weight loss compared to diet pills, with expected weight loss ranging from 25-35%. However, surgery comes with its own set of risks and side effects, including infection, bleeding, nausea, vomiting, and nutritional deficiencies. Additionally, surgery may not be suitable for everyone, especially those with contraindications or who are at high risk.
In conclusion, both diet pills and weight loss surgery are effective tools for weight loss, but they cater to different needs. Diet pills are more suitable for individuals with moderate obesity who are willing to commit to long-term medication use and lifestyle changes. On the other hand, weight loss surgery is a more drastic measure recommended for individuals with higher BMIs who need rapid and substantial weight loss. It is important to consult with a healthcare professional to determine which option is best suited to an individual's specific needs and circumstances.

FDA-approved diet pills for children
In the United States, the Food and Drug Administration (FDA) has approved the use of certain weight management medications for children. These medications are intended for children who are obese or overweight and have associated weight-related medical problems. It is important to note that these medications should be used in conjunction with a healthy diet and exercise regimen, and they do not replace the need for physical activity and healthy eating habits.
One such medication is Wegovy, which is a brand name for semaglutide, a GLP-1 receptor agonist. It was approved by the FDA in 2021 for use in adults and children aged 12 years or older with obesity. The dose must be gradually increased over 16 to 20 weeks to reach the recommended 2.4 mg dosage. This gradual progression helps to reduce potential side effects, which may include gastrointestinal symptoms, headache, dizziness, and fatigue. It is intended for long-term use and should be combined with a healthy diet and exercise.
Other FDA-approved prescription appetite suppressants for long-term use include Liraglutide (Saxenda®), which is administered via subcutaneous injection, and Naltrexone-bupropion (Contrave®), which is a pill. Phentermine-topiramate (Qsymia®) is another pill that has been approved by the FDA, but it is typically prescribed for short-term use, up to 12 weeks.
While these medications can aid in weight management, it is important to consult a healthcare provider before starting any new medication, especially for children. Additionally, it is worth noting that some weight management medications can interfere with hormonal birth control and are not approved for use during pregnancy.

Prescription vs. over-the-counter diet pills
Prescription appetite suppressants are medications that require a doctor's prescription and are regulated by the U.S. Food and Drug Administration (FDA). They are typically recommended for individuals with obesity, which is classified as having a body mass index (BMI) of 30 or higher. Prescription appetite suppressants work by blocking or increasing certain hormones, neurotransmitters, or peptides to reduce hunger or increase feelings of fullness. While they can be effective in weight loss, they may also come with side effects such as rapid heartbeat, mood changes, cognitive issues, nausea, and abdominal pain.
On the other hand, over-the-counter (OTC) diet pills are readily available without a prescription in vitamin shops and drugstores. The only FDA-approved OTC weight-loss medicine currently is Alli (orlistat), which is intended for adults with a low-fat, low-calorie diet. Other OTC products are considered supplements and are not regulated by the FDA, raising concerns about their safety and effectiveness. These products may contain banned substances or interact negatively with other medications, leading to potential health risks. Therefore, it is crucial to consult a healthcare provider before taking any OTC weight-loss products.
Prescription weight-loss pills are often recommended for individuals with specific medical conditions, such as high blood pressure, type 2 diabetes, or high cholesterol, in addition to obesity. Healthcare professionals can monitor patients' progress and adjust dosages or medications accordingly. They consider factors such as lifestyle, BMI, and potential side effects. Prescription pills are generally more effective when combined with lifestyle changes, including a nutritious diet and regular exercise.
In contrast, OTC weight-loss pills may not require lifestyle changes but can still aid in weight loss for some individuals. However, it is important to note that these pills are not a replacement for a healthy diet and exercise regimen. While OTC pills are more accessible, they may not be suitable for everyone, and their effectiveness can vary. Additionally, some OTC products may contain hidden or banned ingredients, such as sibutramine, which was removed by the FDA due to its association with mood changes and increased blood pressure.
Both prescription and OTC diet pills can play a role in weight management. However, it is crucial to understand their differences, potential side effects, and interactions with other medications. Consulting a healthcare provider is essential to determine the safest and most effective option for your specific needs. They can provide guidance on the suitability of different pills, considering your medical history, allergies, and current medications.
