It is a frightening fact that increasing numbers of people worldwide are gaining weight; this problem is now affecting a large number of children of school entry age. To cure this problem, some people have resorted to surgical measures whereas others have decided that adjustments to their food intake and an increase in physical activity are necessary. Impatience to see results usually means that overweight people can frequently resort to using weight loss drugs to achieve that fast result they crave.

These drugs usually work buy telling the brain it's no longer hungry, stimulating metabolism to aid the shedding of excess fat. 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side effects from this type of drug was the increased risk of heart valve disease and of course the drug was quickly withdrawn from use. Not to be defeated though, manufacturers have introduced updated drugs, prescribed by doctors but the FDA approval process is slow.

The chances are that if you asked enough people, someone will say they have used them and been happy with the results. This is obviously a very tempting prospect, to lose weight whilst eating the same diet. The weight loss drug manufacturers have spent a huge sum on research but this cannot be compared to the amount spent by consumers.

Even with all the testing and new techniques available for manufacturers, many side effects like nausea and diarrhea still exist with the new generation of weight control pills which, incidentally, can still be purchased over the counter. 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 best course of action before taking any type of pill is to consult your doctor; here are many factors that could contribute to any problems you experience and these do not necessarily stop when you cease taking the pills. Problems like depression, nausea, bad mood swings, nightmares, insomnia for example have all been reported when a person has stopped taking the weight control pills.

Despite all the bad publicity, weight loss drugs do work but they are more successful if they are used in conjunction with a low calorie diet and regular exercise, preferably using a properly worked out exercise regime. This means eating a good diet containing food from all the food groups that includes vitamins and minerals; fiber can be found in oats, rice, potatoes, cereals, vegetables and fruits.

Of course this should always be combined with a good exercise routine which will use up excess calories and provide a good all round fitness workout. The most efficient exercise should be regular and contain a mixture of cardiovascular (walking, swimming etc.) and weight training using machines to build muscle, burn off excess calories and lose the extra pounds.
