2 examples of deficiency disease

Here are two examples:

1. Scurvy: This disease is caused by a deficiency of vitamin C. Symptoms include fatigue, bleeding gums, and poor wound healing. It is often associated with a lack of fresh fruits and vegetables in the diet.
2. Rickets: This disease is caused by a deficiency of vitamin D, calcium, or phosphate. It leads to soft and deformed bones in children. Sunlight exposure and dietary intake of vitamin D are crucial for prevention.
