What are the major symptoms of rickets?

The major symptoms of rickets include:

- Bone pain and tenderness: Rickets can cause pain and tenderness in the bones, particularly in the legs, arms, and spine. This pain may worsen with activity or pressure on the affected bones.

- Muscle weakness: Rickets can also cause weakness in the muscles, leading to difficulty walking, climbing stairs, or lifting objects.

- Bone deformities: Rickets can cause the bones to become soft and weakened, leading to deformities such as bow legs (inward curvature of the legs), knock-knees (outward curvature of the knees), or a pigeon chest (protrusion of the breastbone).

- Growth retardation: Rickets can stunt growth, leading to children being shorter than their peers.

- Delayed motor skills: Rickets can cause delays in the development of motor skills, such as crawling, walking, or talking.

- Increased risk of fractures: Rickets can weaken the bones, making them more susceptible to fractures.

- Cranial deformities: In severe cases, rickets can cause deformities of the skull, such as a large forehead, broad jaw, and delayed closure of the fontanelles (soft spots on the baby's head).

- Dental problems: Rickets can also cause dental problems, such as delayed tooth eruption, weak teeth, and increased risk of cavities.
