Losing weight is a major concern for many people, and access to diet pills to assist with losing that weight is fairly easy, but how safe are those dietary supplements and pills constantly marketed on television and through other resources?
Among the many possible risks associated with taking diet pills to lose weight, the leader of the pack appears to be heart related complications, with many other documented cases of heart valve deficiencies, metabolism interruptions, pill dependencies, high blood pressures, pulmonary hypertensions, heart palpitations, impotence, insomnia, libido changes, stomach pains, convulsions, erectile dysfunctions, irregular heartbeats, especially if the pills are any number of the cheap, sold over the counter varieties that do not require prescriptions, but have not been tested by the government or are not subject to label or dosage requirements, those that have ingredients similar to amphethamines, those that create laxative effects, which is how diet supplements are designed to work to quickly eliminate water weight, and death.
Two Food and Drug Administration approved diet pills are Orlistat, that blocks the absorption of fat and is not consumed by the body, and Sibutramine, that people with pre-existing heart problems before starting on these pills should avoid because they lower blood pressure. The FDA also recommends the popular diet pill Phentermine not be taken any longer than twelve weeks.
Marketed in most countries as the over the counter Alli, and known as tetrahydrolipstatin, Orlistat is designed to prevent fat absorption and reduce caloric intake, achieving modest results, modest blood pressure reductions, and may help prevent the onset of Type 2 Diabetes, however, Orlistat is well known for its gastrointestinal side effects, which may include such things as oily loose stools, fecal incontinence, frequent bowel movements, flatulence, hypertension, the need for aversion fat therapy, a potential serious risk of liver toxicity, possible liver failure, possible reductions of ciclosporin plasma levels used to prevent organ transplant rejections, impaired antiarrhythmic amiodarone absorptions of the heart, cardiovascular diseases, reduced gallbladder functions, obstructed bile ducts, pancreatic diseases, inhibited pancreatic lipases in the intestines causing undigested trigylcerides to be eliminated from the body, and should not be taken by pregnant women or breast-feeding Mothers. People on Orlistat have also shown a propensity to regain lost weight after stopping the pills.
The Schedule IV controlled substance known as the Sibutramine appetite suppressent, and marketed under the brand name Meridia, is currently under review by the Food and Drug Administartion because of several safety concerns associated with such things as cardiovascular events, increased heart attack and strokes, severe muscle pains, paradoxically increased appetites, increased blood pressures, paresthesias of the skin, serious mood changes, cardiac arrhythmias, seizures, melenas, chest pains, high fever chills, jaundice, hematemesis, dyspnea, shortnesses of breath, hemiplegia weaknesses, edemas, abnormal visions, several clinically significant interactions with other medications, ongoing studies relating to sudden death, renal failures, heart failures, gastrointestinal problems, resuscitated cardiac arrests, and more than sixty known counterfeit weight loss products in the United States containing illegal amounts of Sibutramine being sold as dietary supplements.
Approved in 1959 by the FDA, and first available in the early 1970s, Phenyl-tertiary-butylamine, an amphetamine-class diet pill, and a Schedule IV controlled substance, found in generic forms, and designed for short term weight loss in obese people, releases norepinephrine chemicals into the brain to help control appetite through the fight-or-flight response, adrenaline outside the brain causing fat cells to break down stored fat, dopamine that affects the symphathetic nervous system, and serotonin that affects the central nervous system.
People recommended not to take Phentermine include those with allergic reactions to diet pills, those with glaucoma, overactive thyroids, or severe high blood pressures, those with drug abuse addictions, breast-feeding Mothers, pregnant women, those on any other prescription or non-prescription medications, dietary supplements, or herbal preparations, those with spinal cord or brain disorders, those with high cholesterol or high lipid levels, those with hardening of the arteries, and those on certain medications.
