Prescription Weight-loss Drugs

 
Thinking of trying a prescription weight-loss drug? Read this first.
Under normal circumstances, a calorie-restricted diet and plenty of moderate-to-vigorous exercise should be enough to help you lose weight.

However for those whose BMI falls in the category of 'obese', prescription weight-loss medications may provide an extra boost to help you shed pounds. This is particularly useful for those with obesity-related health conditions, pan
Under normal circumstances, a calorie-restricted diet and plenty of moderate-to-vigorous exercise should be enough to help you lose weight.

Two approaches

Prescription weight-loss dugs have two treatment approaches: suppressing appetite or inhibiting fat absorption.

Appetite suppressants, eg, phentermine, are available as tablets or extended-release capsules designed to release the medication over a period of time. This type of drug fools the body into thinking it is not hungry by altering the levels of brain chemicals associated with mood and appetite.
Fat absorption inhibitors interfere with the body's way of breaking down and absorbing dietary fat. This drug blocks the absorption of roughly 30% of fat, which is then discarded from the body through bowel movements.
Orlistat is an example of a fat absorption inhibitor.

The risks
Prescription weight-loss drugs sound like a dream come true, but beware of the poisoned apple. These drugs are accompanied by their fair share of health hazards, including:
● Addiction. Prescription weight-loss medications are controlled substances. Abuse may lead to dependence.

● Developed tolerance.
These drugs begin to lose their effectiveness around six months after use. This could be attributed to either a tolerance to the medication or that the drug has simply reached its limit in effectiveness.

● Side-effects. While most side effects resulting from prescription weight-loss drugs are bearable, some may be harder to deal with.
These include sweating, digestion problems, insomnia, drowsiness, dizziness, headache, dry mouth, anxiety and an accelerated heart rate. More serious side-effects are rare, but they have been documented.

● Malnourished. As fats are a carrier for vitamins A, D, E, K, your body may be lacking in these important nutrients. To compensate for this lack, your doctor will prescribe nutritional supplements, but you must religiously take them.

The bottom-line
Prescription weight-loss drugs may be useful, but they are not a cure-all for obesity. They are not an alternative to healthy eating and exercise, and not for long-term use. As with other medications, follow your doctor's orders strictly when you are on these drugs.
