There are Different Factors that causes weight gain and some can be controlled while others can't be controlled.

Here are seven causes of Weight gain that can't be controlled.

1. You're Depressed
Many anti-depressant medications cause weight gain--so if you're depressed and taking pills for it, expect to see a bump in weight between 5 and 15 pounds, with continued gradual accumulation over the years, says Dr. Hedaya, who is also the founder of the National Center for Whole Psychiatry in Chevy Chase, MD. If you're not taking pills, there's evidence that feelings of depression can correlate to weight gain.



2. You're Taking The Wrong Rx
There's a long list of medications that can cause weight gain: If you're taking birth control pills, excess hormones for hormone therapy, steroids, beta-blockers for heart disease and blood pressure, anti-seizure meds, breast cancer medications like Tamoxifen, some treatments for rheumatoid arthritis, and even some migraine and heartburn medications, you may notice pounds creeping on.



3. Your Gut Is Slow
Digestive issues, including slow bowel movements, may also account for excess pounds. "Ideally, you eat, and then, an hour or so later, you have a bowel movement," says Dr. Hedaya. "But once or twice a day is still in the healthy range." If you're not so regular, dehydration, medications, low fiber, or even a lack of good flora in your gut could be to blame.





4. Your Body Doesn't Have Enough Of Certain Nutrients
Being low in vitamin D, magnesium, or iron can compromise your immune system, sap your energy levels, or alter your metabolism in ways that make it harder to take healthy-lifestyle steps. "You may compensate for low energy with caffeine, sweets, and simple carbs," says Dr. Hedaya, "Or find that you feel too run down or weak to exercise."







5. You're Getting Older
It's the one condition that's unavoidable."Often, I hear patients tell me they think their metabolism is slowing down," says Dr. Fradin-Read. "This is real--we don't burn as many calories at 40 or 50 as we used to burn at 20. So we need more exercise--and less food--to keep metabolism going. Some studies show that exercise might be even more important than the diet for long-term weight maintenance."




6. You Have Plantar Fasciitis
"Many musculoskeletal conditions, including plantar fasciitis, but also osteoarthritis and knee or hip pain, can result in unintentional weight gain," says Donald Bohay, MD, cochairman of the public education committee for the American Orthopaedic Foot & Ankle Society. "Plantar fasciitis certainly can force you to cut back on your activity enough to cause weight gain."







7. You Have Cushing's Syndrome
Weight gain accompanied by high blood pressure, osteoporosis, and changes in your skin tone and quality, including purple or silvery stretch marks on your abdomen and ruddy cheeks, could be a sign that your body isn't processing nutrients the way it should, due to a cortisol-producing tumor on one of your adrenal glands. The syndrome affects only about 15 in every million adults annually, so proceed with caution before demanding a battery of tests. "Cushing's Syndrome is not terribly common," says Dr. Wittlin, "but one of the telltale signs is that your fat distribution is more in the midsection of your body, leaving your arms and legs looking more slender."
