Bone Health: Preventing and Treating Low Bone Density

What causes bone loss/bone density? Learn more about bone health

Bones are living tissue with blood flow and active metabolism. They respond to diet and exercise by getting stronger, and they store minerals your body needs, especially calcium. Throughout life the body breaks down old bone (resorption) and builds new bone. If resorption outpaces formation, net bone loss occurs. That can cause low bone density (osteopenia), weak bones, and eventually osteoporosis, which raises fracture risk even after minor falls.

How osteoporosis develops

Most bone is added during childhood and the teen years, so peak bone mass usually occurs around age 30. After that, resorption slowly exceeds formation and bone mass declines. Women lose bone fastest in the first years after menopause, when estrogen falls. Men also lose bone with age, and by about age 65 their loss rate matches women.

Common contributors to bone loss

• Low calcium intake and poor vitamin D status
• Inactivity and lack of weight-bearing exercise (exercise)
• Smoking and excessive alcohol use
• Long-term corticosteroid use and certain medical conditions (arthritis, asthma, Crohn's disease, lupus)
• Hormone deficiencies, including low estrogen in women and low testosterone in men

Corticosteroids are commonly prescribed for inflammatory conditions and can cause osteoporosis when used chronically. Other medical problems can also reduce bone quality or interfere with calcium and vitamin D metabolism.

The link between anorexia nervosa and low bone density

Anorexia nervosa causes hormonal and nutritional deficits that harm bone. Very low body weight can stop estrogen production in females, causing amenorrhea and rapid bone loss. High cortisol, reduced growth factors, calcium deficiency, and malnutrition all contribute. Men with anorexia may lose bone through low weight, restricted intake, and low testosterone. Studies show low bone mass is common and appears early in the illness; that lowers peak bone mass and raises lifetime fracture risk.

Calc Phos may help with feelings of exhaustion when recovering from an illness. Effective natural therapy for growth problems, including late tooth growth and broken bones. Useful for thin and anemic individuals.

Diabetes and bone fracture risk

People with Type 1 diabetes face higher fracture risk and lower bone mass, and women with Type 1 are much more likely to fracture than women without diabetes. Type 2 diabetes can impair bone quality even when bone mass looks normal. Longer diabetes duration raises fracture risk and slows healing.

Diabetes often coexists with low vitamin D, which reduces calcium absorption and can trigger secondary hyperparathyroidism, increasing bone loss. High blood glucose causes chronic inflammation that weakens bone. Severe vitamin D or calcium deficiency can cause osteomalacia, where new bone fails to mineralize properly.

What you can do

Focus on weight-bearing exercise, adequate calcium and vitamin D, quitting smoking, and limiting alcohol. If you take long-term corticosteroids or have conditions like diabetes or an eating disorder, discuss bone screening and treatment options with your clinician. Early attention protects peak bone mass and lowers fracture risk later in life.
