Appetite Suppressants: A Comprehensive Guide for Singaporeans

Introduction

Appetite suppressants are medications that help reduce hunger and food intake. They are often used as part of a weight loss program to help people lose weight and keep it off. However, it's important to use appetite suppressants under the guidance of a healthcare professional, as they can have side effects.

In Singapore, an estimated 20% of adults are obese and another 30% are overweight, according to the National Population Health Survey 2020. This has led to an increased demand for appetite suppressants, as people seek ways to manage their weight.

How do Appetite Suppressants Work?

Appetite suppressants work by affecting the brain's appetite control center. They can either:

• Increase the levels of hormones that signal fullness (e.g., leptin and cholecystokinin)
• Block the effects of hormones that stimulate hunger (e.g., ghrelin)

As a result, appetite suppressants can help people feel less hungry and eat less food.

Types of Appetite Suppressants

There are two main types of appetite suppressants: prescription and over-the-counter (OTC):

Prescription Appetite Suppressants

Prescription appetite suppressants are available by prescription only. They are typically used when other weight loss methods have not been successful. Prescription appetite suppressants include:

• Stimulants: These drugs increase alertness and activity levels, which can help reduce hunger. Examples include amphetamine and caffeine.
• Non-stimulants: These drugs work by affecting the appetite control center in the brain. Examples include phentermine and lorcaserin.

Over-the-Counter Appetite Suppressants

OTC appetite suppressants are available without a prescription. They are typically less effective than prescription appetite suppressants, but they can still be helpful for some people. OTC appetite suppressants include:

• Fiber: Fiber can help you feel full and eat less food. Examples include glucomannan and psyllium husk.
• Caffeine: Caffeine can help increase alertness and activity levels, which can help reduce hunger.
• Hoodia: Hoodia is a plant that has been shown to have appetite suppressant effects.

Benefits of Appetite Suppressants

Appetite suppressants can help people lose weight and keep it off. They can also improve other health indicators, such as blood pressure and cholesterol levels.

Studies have shown that people who take appetite suppressants can lose more weight than those who do not. For example, a study published in the journal Obesity found that people who took the appetite suppressant phentermine lost an average of 10% of their body weight over a period of 12 weeks.

In addition to weight loss, appetite suppressants can also improve other health indicators. For example, a study published in the journal Diabetes Care found that people who took the appetite suppressant lorcaserin had significant improvements in their blood pressure and cholesterol levels.
