What causes a Vitamin D deficiency?
Vitamin D deficiency results from inadequate dietary intake of preformed vitamin D, malabsorption of vitamin D, or too little exposure to sunlight. This deficiency may also occur in overcrowded urban areas in which smog limits sunlight penetration. Other conditions that can lead to Vitamin D Deficiency are habits such as smoking, diets which lack vitamin D rich foods, consumption of alchohol, stress and environmental factors.

Vitamin D deficiency means you are deficient in vitamin D. Vitamin D is the sunshine vitamin which your body makes from being exposed to sunshine. You can get vitamin D from eating fatty fish like salmon and tuna or beef liver. Some dairy products are fortified with vitamin D and so are some breakfast cereals.
That depends on what you are deficient in. For instance, vitamin C deficiency leads to scurvy. Vitamin D deficiency can cause rickets and osteoporosis. Vitamin B deficiency causes a host of problems including, niacin: pellagra and thiamine: beriberi. Macronutrient deficiency (Carbohydrates, Proteins, and Fats) can cause many problems as well including malnutrition.
The deficiency of vitamins B12 B6 vitamin e and Vitamin d may cause cramps. B12 is responsible for maintaining healthy nerves and blood vessels. its found in meat and dairy products. B6 helps red blood cell metabolism hence is very important. Vitamin E deficiency causes damage to peripheral nervous system causing cramps.
The most common symptom of vitamin A deficiency is impaired vision. Vitamin A deficiency can cause blindness, night blindness and also failure to produce tears. Vitamin C deficiency causes Rickets ( impaired growth, weakening of bones) osteomalacia in adults ie. softening of bones , bending of spine etc.
Osteomalacia is associated with deficiency of Vitamin D (deficiency may be due to low dietry intake, less exposure to sunlight etc). Studies have shown that vitamin D has influence on RBC formation. Vitamin D somehow increases RBC production. Hence osteomalacia secondary to Vitamin D deficiency is associated with anemia.
