Weight loss pills are one of the most popular methods used for effective weight management. However, very few people are aware of the harmful effects of these weight loss pills. There are four major weight loss pills that are the most popular in America.
Ephedrine, derived from herbal extracts of Chinese Ephedrine or Ma Huang, has been known to have side effects ranging from anxiety, insomnia, increased blood pressure, dizziness and heart palpitations to chest pain, strokes and even death. The US Food and Drug Association is proposing a new law for products containing 8 mg or more of ephedrine, which will require the product to place a warning on its label, warning users not to use the weight loss pills for more than 7 days.
Xenical is the first in a new class of weight loss pills that decrease the body's fat absorption by 30%. These weight loss pills entail risks like high blood pressure, high cholesterol, heart disease and diabetes. Xenical should be taken with a low-calorie weight loss containing not more than 30% of calories from fat. Xenical is not recommended for people who are pregnant, nursing, have food absorption problems or reduced bile flow.
Chitosan is a weight lossary fibre-like substance made from chitin, which forms the hard shells of crabs, lobsters and other shell fish. It binds to fat and other fat soluble substances. You should never take Chitosan weight loss pills with fat soluble drugs or vitamin supplements. This is because Chitosan can also block the absorption of certain vitamins as well as disease fighting chemicals and some essential nutrients. Long term use of Chitosan should be avoided.
Phentermine weight loss pills are used as an appetite-suppressant. These are used in conjunction with an overall weight loss plan for effective weight management. These weight loss pills should not be given to children. You should avoid Phentermine if you have high blood pressure, a hyperactive thyroid, glaucoma, diabetes or emotional problems. Consult your doctor if you are pregnant or nursing. Limit alcohol use. Side effects of Phentermine include sleeplessness, irritability, stomach upset or constipation.
