The FDA has given clearance to 23andMe to perform genetic testing for ten diseases. The links are theirs, not mine:

• Early-onset primary dystonia, a movement disorder,
• Factor XI deficiency, a blood clotting disorder,
• Gaucher disease type 1, an organ and tissue disorder in which white blood cells get abnormal sphingolipid deposits,
• Glucose-6-Phosphate Dehydrogenase deficiency, also known as G6PD, a condition that makes red blood cells fragile,
• Hereditary hemochromatosis, a disorder of iron metabolism that leads to excess iron build-up,
• Hereditary thrombophilia, a blood clotting disorder

Big swings in weight may be associated with increased risk of heart attack and stroke. I'm skeptical of the result, but if true, this is yet another way you can improve your chances of a long, healthy life. Eat good foods, get yourself around under human power, get some sleep, and watch your weight hit a natural level for your body. If you're very heavy or having complications of your extra weight, think about bariatric surgery. No need to have your weight swing back and forth 50 pounds a year for the rest of your life.
