Each year, increasing numbers of people around the world are becoming overweight; in addition to these fears shown by health organizations, is the fact that obesity is affecting younger people. In order to lose those excess pounds, many people resort to surgery whereas other people realize that a healthy diet with regular exercise is a better method. Weight reduction should be approached as a long term proposition especially when you consider it takes considerable time to become overweight so the use of weight loss drugs should be used with caution.

The drugs work by increasing the serotonin levels in the brain, making it believe that the stomach is already full, thereby, increasing the person's metabolic rate. The problem arose when it was found that one of the side effects from this type of drug was the increased risk of heart valve disease and of course the drug was quickly withdrawn from use. More recently, new drugs have been developed and prescribed by doctors; many of which are still waiting for FDA approval.

The chances are that if you asked enough people, someone will say they have used them and been happy with the results. To many it is a wonder drug and let's be honest, if you could lose weight that easily without having to sacrifice anything in the process, you would take them as well. As a consequence, drug companies spend millions of dollars in research on weight loss drugs while consumers spend even more buying the pills.

An individual wishing to buy weight control pills can do so over-the-counter or have them prescribed by their doctor; however there are still health risks associated with their use. But they are not the only side effects and some can be more harmful than others. These include heart attacks, tremors, strokes, hallucinations and renal failure.

The side effects vary depending on the lifestyle and health of the person and can be minimized as long as one consults the doctor first before buying them; it should be noted that if one stops using the drugs, the side effects will not necessarily cease. The side effects experienced by users of weight loss pills can include noticeable mood swings, hyper-activity, stomach pains, insomnia, nightmares, severe irritability, extreme fatigue, depression, nausea, vomiting and trembling.

Although these weight loss drugs do work, an increase in beneficial effects occurs when regular exercise is undertaken along with a change in eating habits. A diet that is full of foods such as oats, rice, cereals, potatoes, vegetables and fruits contain a good supply of vitamins, minerals and essential fiber.

Exercising will need to be carried out if you want to benefit from the healthy food option but this probably needs to be worked out in advance with your physician. A good exercise plan with the use of weights will help improve the body's ability to burn off the calories and maintain a healthy heart.
