What is Osteomalacia?

21:55 - 4 May , 2021


It is a bone condition in which the bones cannot be strengthened or mineralized, mainly due to a lack of vitamin D, and although it usually affects the elderly, it can occur at any stage of life because the bones constantly undergo a bone replacement process.

Osteomalacia is not bone loss, as in osteoporosis, but the softening of the bones due to a lack of mineralization as part of the bone-building process, leaving the collagen soft and vulnerable.

This pathology arises due to the following:

  • Low levels of vitamin D due to a poor diet or because the body cannot absorb it, as well as a lack of sunlight exposure.
  • Weight loss surgeries.
  • Celiac disease.
  • Genetic factors.
  • Lack of phosphorus.
  • Antacid medications or to control epileptic seizures.
  • Liver problems.
  • Kidney disorders.
  • Some types of cancer.

Signs and symptoms Osteomalacia

Characteristic symptoms include:

  • Difficulty walking
  • Muscle spasms.
  • Feet and pelvis bone fractures.
  • Bones sensitive to minor shocks.
  • Lumbar and pelvic pain.
  • Sore, weak, and stiff muscles.
  • Sore legs

However, some people may not have symptoms.

Diagnosis and treatment Osteomalacia

Once the doctor analyzes your symptoms and clinical history, they will perform a physical examination and order blood and urine tests to assess.

  • High levels of parathyroid hormones.
  • High levels of alkaline phosphatase.
  • Low calcium levels.
  • Low phosphate levels.

You may also require bone density tests and X-rays to determine how advanced the osteomalacia is. Treatment consists of providing the necessary nutrients for bone mineralization, as well as:

  • Not consuming alcohol.
  • Quit smoking.
  • Taking vitamin D, calcium, and phosphorus supplements constantly.
  • Performing physical activity regularly.
  • Taking daily sunbaths.
