Losing weight is a common goal for many people, and with a large number of weight loss drugs on the market, people naturally seek medical advice on which weight loss drugs are safe and effective. However, the decision to prescribe weight loss pills is not simple for doctors. This article aims to uncover the process and reasons behind what weight loss pills doctors may prescribe.
Understanding weight loss drugs
It is crucial to understand the broad categories of weight loss drugs before delving into the details of prescriptions prescribed by doctors. Generally speaking, weight loss pills can be divided into several types:
Appetite suppressants: These pills work by reducing hunger, making it easier for individuals to stick to calorie restricted diets.
Fat Blockers: These pills can prevent fat from being absorbed in the digestive system, thereby reducing total calorie intake.
Metabolic enhancers: These pills can increase the body’s metabolic rate and help burn more calories throughout the day.
Compound pills: These combine multiple mechanisms of action to achieve weight loss.
The history of weight loss drugs and the reluctance of doctors
The history of weight loss drugs is full of controversies and safety issues. In the 1940s, doctors began prescribing amphetamines for weight loss, but this led to an increase in addiction rates. Then, in the 1990s, a popular combination of weight loss drugs, fen hen, was found to cause serious heart defects. These events have largely led to doctors being unwilling to prescribe weight loss pills today.
Despite advances in medication safety, current weight loss drugs can only produce moderate weight loss effects. However, as obesity is increasingly recognized as a treatable disease, doctors face the challenge of balancing the benefits and risks of these medications.
Factors affecting prescription decisions
There are several factors that can affect whether a doctor will prescribe weight loss medication:
FDA approval: Only a small percentage of doctors regularly prescribe weight loss drugs currently approved by the US Food and Drug Administration (FDA). This is because the FDA’s approval process ensures that the benefits of a drug outweigh its risks.
Side effects: Although current drugs are much safer than past drugs, they still have side effects. These symptoms range from mild (such as dry mouth, constipation) to severe (such as palpitations, hypertension). Doctors must weigh the potential benefits of weight loss against these risks.
Patient’s health history: Doctors will consider the overall health status of the patient before prescribing weight loss medication. Diseases such as heart disease, high blood pressure or diabetes may make some diet pills unsuitable.
Patient motivation and commitment: Weight loss pills are not a panacea for weight loss. They work best when combined with diet and exercise. Therefore, doctors will evaluate the patient’s motivation and commitment to changing their lifestyle before prescribing medication.
Types of weight loss pills prescribed by doctors
Despite the above hesitation, doctors may prescribe specific types of weight loss pills based on the individual needs of patients:
Orlistat (Xenical, Alli)
Mechanism of action: Orlistat is a fat blocker that prevents the absorption of approximately 30% of the fat consumed in a meal.
Prescription criteria: It is usually used for individuals with a BMI of 30 or higher, or people with a BMI of 27 or higher and at least one weight related complication (such as diabetes, hypertension).
Side effects: Common side effects include bloating, bloating, and oily stools. More serious side effects may include liver damage and kidney stones.
Phentermine (Adipex-P, Lomaira)
Mechanism of action: Fentemine is an appetite suppressant that works by increasing the levels of neurotransmitters in the brain that reduce appetite.
Prescription standard: It is typically prescribed for short-term use (up to 12 weeks) as part of a comprehensive weight loss plan. It is suitable for individuals with a BMI of 30 or higher, or those with a BMI of 27 or higher and weight related health issues.
Side effects: Side effects may include increased heart rate, hypertension, insomnia, and dry mouth.
Liraglutide (Contrave)
Mechanism of action: Liraglutide is a glucagon like peptide-1 (GLP-1) receptor agonist that increases satiety and slows down gastric emptying.
Prescription standard: It is suitable for adults with a BMI of 30 or higher, or adults with a BMI of 27 or higher and at least one weight related complication.
Side effects: Side effects may include nausea, vomiting, diarrhea and hypoglycemia (especially in patients with diabetes).
Liraglutide (Saxenda)
Mechanism of action: Liraglutide is a glucagon like peptide-1 (GLP-1) receptor agonist that increases satiety and slows down gastric emptying.
Prescription standard: It is suitable for adults with a BMI of 30 or higher, or adults with a BMI of 27 or higher and at least one weight related complication.
Side effects: Side effects may include nausea, vomiting, diarrhea and hypoglycemia (especially in patients with diabetes).
Non prescription alternative therapy and complementary therapy
Although weight loss pills can be useful tools for weight loss, they cannot replace a healthy diet and regular exercise. Doctors usually recommend the following over-the-counter alternative and complementary therapies:
Lifestyle changes: Adopting healthy eating habits and regular physical exercise are the cornerstone of weight loss. This includes a balanced diet rich in fruits, vegetables, whole grains, and lean protein, as well as at least 150 minutes of moderate intensity aerobic exercise per week.
Behavioral therapy: Cognitive behavioral therapy (CBT) can help individuals identify and change unhealthy eating habits, and increase motivation to lose weight.
Weight loss surgery: For individuals with severe obesity (BMI of 40 or higher) or BMI of 35 or higher and at least one obesity related complication, weight loss surgery may be an option. This includes surgeries such as gastric bypass surgery and sleeve gastrectomy.
Alternative therapy: Some people may find alternative therapies, such as acupuncture and moxibustion, hypnotherapy or herbal supplements, helpful in their weight loss journey. However, it is important to note that these therapies have not been widely researched and may not be effective for everyone.
The role of antidepressants in weight loss
It’s worth mentioning that antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs) like fluoxetine (Prozac), have been found to have weight-loss effects in some individuals. This is particularly true for those who eat due to emotional or stress-related reasons. Antidepressants can help regulate mood and reduce the urge to eat as a coping mechanism. However, they are not prescribed solely for weight loss and should only be used under a doctor’s supervision.
Conclusion
The decision to prescribe diet pills is a complex one that involves multiple factors, including the patient’s health status, motivation, and the potential benefits and risks of the medication. While diet pills can be a useful tool in weight loss, they are not a substitute for healthy eating and regular exercise. Therefore, doctors often recommend a combination of lifestyle modifications, behavioral therapy, and, in severe cases, bariatric surgery.
It’s important for individuals seeking weight loss to consult with a healthcare professional to determine the most appropriate and effective treatment plan. With the right approach, weight loss is achievable and can lead to improved health and well-being.
