Pharmaceuticals In, Pounds Off

Some of this talk about weight-loss drugs might not seem relevant to childhood obesity, but the connection is, obese children tend to become obese adults. To learn about the possibilities is to fervently wish that our children will never have to experience them firsthand.

Orlistat (generic) comes in two brand names that denote different dosages. It is said to block absorption of 25 percent of the fat in a meal, and is recommended for very obese patients who are coping with the risk factors of hypertension, diabetes, or hyperlipidemia. The daunting list of side effects would seem to preclude any kind of social life.

Lorcaserin is an extended-release tablet that helps people feel fuller with smaller meals, by affecting the brain’s appetite-controlling signals. As expected, it comes with warnings about pre-existing conditions and possible conflicts with other medications. As always, the patient is enjoined to practice good dietary and exercise habits.

Lorcaserin has worrisome physical side effects and even more alarming mental effects, including impaired thinking, decreased alertness, urges to self-harm, and out-of-body sensations. It is not to be prescribed to people under 18.

Metformin is described by a patient Marcia Kadanoff (as told to writer Timothy Hay) as safe, effective, and affordable; not very stressful to the internal organs; and not linked to weight gain. Its primary use is the treatment of diabetes, and it is in fact (although not officially approved as such) also a weight-loss drug. The authors say of this member of the class biguanides:

The medicine does not increase insulin levels in the body, but instead lessens the amount of sugar the body produces and absorbs. As it lowers glucose production in the liver, metformin also lowers blood sugar by increasing the body’s sensitivity to insulin. It also decreases the amount of glucose that our bodies absorb from the foods we eat.

I expected it to work like insulin in pill form and drop my blood sugar (around 180 mg/dl at the time) right away. But… It can take four or five days to experience the full benefit, depending on your dosage.

Some patients experience side effects, which usually subside over time. They might include nausea, stomach pain, gas, bloating, and diarrhea. To prevent these discomforts, doctors like to start conservative and titrate up, which may delay the perceived start of the benefits even more.

Reportedly, gastric distress can be alleviated by avoiding carbohydrates in the diet, or by using the extended-release version of the medication. Also, metformin can block the absorption of Vitamin B12, so that needs to be monitored.

The more serious, alarming, and fortunately rare side effects include hypoglycemia, lactic acidosis, liver damage, and heart failure. On the plus side, metformin is being looked at for a variety of other uses including, paradoxically, heart disease.
