1. Diabetes: A metabolic disorder characterized by high blood sugar levels due to the body's inability to produce or effectively use insulin.
2. Obesity: A condition characterized by excessive body fat accumulation, often caused by an imbalance between calorie intake and energy expenditure.
3. Hyperthyroidism: A condition in which the thyroid gland produces an excessive amount of thyroid hormones, leading to an increased metabolic rate.
4. Hypothyroidism: A condition in which the thyroid gland does not produce enough thyroid hormones, resulting in a decreased metabolic rate.
5. Phenylketonuria (PKU): A genetic disorder in which the body cannot break down the amino acid phenylalanine, leading to its accumulation in the blood and brain.
6. Galactosemia: A genetic disorder in which the body cannot break down galactose, a sugar found in milk, leading to its accumulation in the blood and tissues.
7. Gout: A form of arthritis caused by the buildup of uric acid crystals in the joints, resulting in inflammation and pain.
8. Cystic fibrosis: A genetic disorder that affects the lungs, pancreas, and other organs, causing the production of thick, sticky mucus that can obstruct the airways and impair digestion.
9. Wilson's disease: A genetic disorder that causes copper to accumulate in the liver, brain, and other organs, leading to liver disease, neurological symptoms, and other complications.
10. Alkaptonuria: A rare genetic disorder in which the body cannot break down the amino acids phenylalanine and tyrosine, leading to the accumulation of a pigment called homogentisic acid in the connective tissues, causing dark urine and joint problems.
