As a medical professional with a focus on bone health, I can provide a comprehensive explanation on the causes of rickets in adults, which is more accurately termed as osteomalacia in this age group.
Rickets is a disease that primarily affects children and is characterized by soft and weak bones due to a deficiency of vitamin D. However, when similar symptoms occur in adults, the condition is referred to as osteomalacia. The primary cause of osteomalacia in adults is also a deficiency of vitamin D, which is essential for the absorption and utilization of calcium and phosphorus, two minerals critical for bone health.
Vitamin D Deficiency: Vitamin D is either obtained through the diet, synthesized in the skin upon exposure to ultraviolet B (UVB) rays from the sun, or taken as a supplement. Deficiency can occur due to inadequate dietary intake, lack of sun exposure, malabsorption syndromes, or conditions that affect the liver and kidneys, as these organs play a crucial role in converting vitamin D into its active form.
Inadequate Sun Exposure: The body synthesizes vitamin D when the skin is exposed to sunlight. However, living at higher latitudes where UVB rays are less intense, long winters with limited sunlight, or wearing clothing that covers most of the skin can lead to insufficient vitamin D production.
Malabsorption Syndromes: Conditions such as celiac disease, inflammatory bowel disease, and pancreatic insufficiency can impair the body's ability to absorb dietary vitamin D and other nutrients, leading to deficiency.
Liver and Kidney Disease: The liver and kidneys are essential for converting vitamin D into its active form. Conditions that affect these organs, such as liver cirrhosis or chronic kidney disease, can lead to a deficiency in the active form of vitamin D, which in turn causes osteomalacia.
Other Factors: Certain medications, such as anticonvulsants and glucocorticoids, can interfere with vitamin D metabolism. Additionally, obesity has been linked to lower levels of vitamin D due to sequestration of the vitamin in adipose tissue.
Symptoms of Osteomalacia: In adults, symptoms can include bone pain, muscle weakness, and in severe cases, fractures or deformities can occur. The diagnosis typically involves a combination of physical examination, blood tests to measure levels of calcium, phosphorus, and vitamin D, and imaging studies such as X-rays or bone scans.
Treatment: The primary treatment for osteomalacia involves correcting the underlying cause, which often means addressing the vitamin D deficiency. This can be done through supplementation, dietary changes, and ensuring adequate sun exposure. In some cases, treatment of the underlying disease or condition is necessary.
Prevention: To prevent osteomalacia, it is important to maintain adequate levels of vitamin D through diet, sunlight exposure, and possibly supplementation, especially for those at risk due to factors such as living at high latitudes, having limited sun exposure, or having certain medical conditions.
In conclusion, while rickets is a disease of childhood, the underlying issue of vitamin D deficiency can also lead to osteomalacia in adults. Ensuring adequate vitamin D levels through diet, sunlight, and supplementation is crucial for maintaining bone health and preventing this condition.

When it occurs among children the disorder is called rickets and usually is due to a deficiency of vitamin D. Rickets was a common disease among youngsters in northern latitudes before milk was fortified with vitamin D. Other causes of osteomalacia include inadequate exposure to the sun's ultra violet rays (which allow ...Jun 22, 2005
