Obesity can wreak havoc on your feet and ankles.
Multiple studies have linked a higher BMI (body mass index) with foot and ankle problems, and even amounts as small as an extra 10 pounds can cause issues.
The problems we see most often that are associated with weight are plantar fasciitis, arthritis and posterior tibial tendonitis - all painful.
It has been estimated that every pound of body weight causes three pounds of force that your feet have to absorb when you're walking, and seven pounds when running.
That means a 200 pound person's feet would be subject to 600 pounds of force with every step and 1,400 pounds of force when running.
Our feet were designed to withstand a certain amount of force, so extra weight can cause all sorts of problems with your feet, ankles and knees.
With every extra pound you carry, your risk increases for osteoarthritis, stress fractures, tendonitis, plantar fasciitis, flat feet, pronation, bunions, hammertoes, heel spurs, frequent ankle sprains, shin splints and all types of pain.
Not to mention the fact that obesity increases your risk of type II diabetes, which leads to peripheral neuropathy disease. This is the #1 reason why people have to have their feet, toes, legs, hands and arms amputated.
The Centers for Disease Control has some great information about living healthy.
