Some anti-obesity drugs can have severe, even, lethal side effects, fen-phen being a famous example. Fen-phen was reported through the FDA to cause abnormal echocardiograms, heart valve problems, and rare valvular diseases. One of, if not the first, to sound alarms was Sir Arthur MacNalty, Chief Medical Officer (United Kingdom). As early as the 1930s, he warned against the use of dinitrophenol as an anti-obesity medication and the injudicious and/or medically unsupervised use of thyroid hormone to achieve weight reduction. The side effects are often associated with the medication's mechanism of action. In general, stimulants carry a risk of high blood pressure, faster heart rate, palpitations, closed-angle glaucoma, drug addiction, restlessness, agitation, and insomnia.
MyPlace is a calorie counting app. With it, you can manage your diet and check out what you're eating. Its database contains over two million items. There is also a barcode scanner so you can quickly add items to your list. It also tracks your water intake. The basic idea of an app like this is that you can tweak and manage your diet over time to eat healthier items and fewer calories. The result is (usually) weight loss. The app is well designed and you can try it for free before paying for the subscription. Those who do go with the subscription will get advanced stats, a private board in their forums, and priority customer support.
Gastric Bypass: Your doctor may call this "Roux-en-Y" gastric bypass, or RYGB. The surgeon leaves only a very small part of the stomach (called the pouch). That pouch can't hold a lot of food, so you eat less. The food you eat bypasses the rest of the stomach, going straight from the pouch to your small intestine. This surgery can often be done through several small incisions using a camera to see inside (laparoscope). Doctors can also perform a mini-gastric bypass, which is a similar procedure also done through a laparoscope.
The duodenum, or the first portion of the small intestine, is divided just past the outlet of the stomach. A segment of the distal (last portion) small intestine is then brought up and connected to the outlet of the newly created stomach, so that when the patient eats, the food goes through a newly created tubular stomach pouch and empties directly into the last segment of the small intestine. Roughly three-fourths of the small intestine is bypassed by the food stream.
Bupropion-naltrexone is a combination drug. Naltrexone is used to treat alcohol and opioid dependence. Bupropion is an antidepressant and quit-smoking aid. Like all antidepressants, bupropion carries a warning about suicide risk. Bupropion-naltrexone can raise blood pressure, and monitoring is necessary at the start of treatment. Common side effects include nausea, headache and constipation.
