Vitamin D is important for bone and muscle health and may help prevent diseases. It is produced by sunlight exposure and is important for calcium absorption. A lack of vitamin D can lead to rickets in children, causing soft and misshapen bones, and osteomalacia in adults, causing bone pain and weakness. While vitamin D deficiency has negative health effects, too much can also be harmful.

3. Vitamin D is important for good health, growth and strong bones. A
lack of vitamin D is very common. Vitamin D is mostly made in the
skin by exposure to sunlight. Most foods contain very little vitamin D
naturally, though some are fortified (enriched)

4. A main action of vitamin D is to help calcium and phosphorus in our
diet to be absorbed from the gut. Calcium and phosphorus are needed
to keep bones healthy and strong. So, vitamin D is really important for
strong and healthy bones. In addition, vitamin D seems to be important
for muscles and general health. There is also some evidence that
vitamin D may also help to prevent other diseases such as cancer,
diabetes and heart disease.

5. People can become deficient in vitamin D because they don't
consume enough or absorb enough from food, their exposure to
sunlight is limited, or their kidneys cannot convert vitamin D to its
active form in the body. In children vitamin D deficiency causes
rickets, where the bones become soft and bend. It's a rare disease but
still occurs, In adults, vitamin D deficiency leads to osteomalacia,
causing bone pain and muscle weakness

6. Vitamin D is being studied for its possible connections to several
diseases and medical problems.
Vitamin D Deficiency leads to:
Rickets in small children.
Osteomalacia

7. Fatigue
Muscle pain and weakness
Joint pain
Chronic pain
Weight gain
Restless sleep
Headaches
Bladder problems

8. Rickets is a condition that affects bone development in children. It causes the bones to
become soft and weak, which can lead to bone deformities.
In rare cases, children can be born with a genetic form of rickets. It can also develop if
another condition affects how vitamins and minerals are absorbed by the body.
Signs and symptoms of rickets
Rickets can lead to bone pain, poor growth and deformities of the skeleton, such as bowed
legs, curvature of the spine and thickening of the ankles, wrists and knees.
Children with rickets are also more likely to fracture their bones
How to prevent rickets
Rickets can easily be prevented by eating a diet that includes vitamin D and calcium, as well
as spending some time in sunlight.

9. Osteomalacia is softening of the bones due to a lack of vitamin D or a problem with the body's ability to break
down and use this vitamin
There are many causes of osteomalacia.
Other conditions that may lead to osteomalacia include:
Not enough vitamin D in the diet
Not enough exposure to sunlight, which produces vitamin D in the body
Malabsorption of vitamin D by the intestines
Symptoms:
. Bone fractures that happen without a real injury
Muscle weakness
Widespread bone pain, especially in the hips

10. Yes, when amounts in the blood become too high. Signs of toxicity
include nausea, vomiting, poor appetite, constipation, weakness, and
weight loss. And by raising blood levels of calcium, too much vitamin
D can cause confusion, disorientation, and problems with heart.
Excess vitamin D can also damage the kidneys.
