Human Diseases
In modern medical science Human diseases are not just random occurrences. They are meticulously classified based on their causes, the body parts they affect, and the mechanisms they employ. This classification system is a matter of interest and a shared responsibility. This guide will demystify the different types of human diseases, providing clear and detailed explanations for each category. In the Tibb-e-Unani medicine system, all these diseases come under temperament. In future articles, we will delve into their treatment through Tibb-e-Unani, arming you with the knowledge to make informed decisions about your health.
Infectious Diseases
Definition: Infectious diseases, a significant threat to our health, are caused by pathogenic microorganisms like bacteria, viruses, fungi, and parasites. These Human diseases can spread from one person to another directly or indirectly, underscoring the importance of prevention and early detection.

Genetic and Congenital Diseases
Definition: Genetic Human diseases are caused by abnormalities in an individual’s DNA, while congenital diseases are conditions present from birth that may be due to genetic or environmental factors.
Types and Examples:
1. Single-Gene Disorders:
– Cystic Fibrosis: Caused by mutations in the CFTR gene, it affects the respiratory and digestive systems.

– Type 2 Diabetes: Involves multiple genes and lifestyle factors.
4. Congenital Malformations:
– Cleft Lip and Palate: A congenital disability affecting the upper lip and the roof of the mouth.
– Spina Bifida: A neural tube defect that affects the spine.
Autoimmune Diseases
**Definition**: Autoimmune diseases occur when the immune system mistakenly attacks the body’s cells and tissues.
Types and Examples:

2. Rheumatoid Arthritis: Causes inflammation of the joints, leading to pain and swelling.
3. Type 1 Diabetes: The immune system attacks insulin-producing cells in the pancreas.
4. Multiple Sclerosis (MS): The immune system attacks the protective covering of nerves, leading to neurological symptoms.
Metabolic Disorders
Definition: Metabolic disorders result from abnormal chemical reactions in the body’s metabolism.
Types and Examples:
1. Diabetes Mellitus:

– Type 2 Diabetes: The body becomes resistant to insulin.
2. Hyperthyroidism: The thyroid gland produces excessive hormones.
3. Hypothyroidism: The thyroid gland produces insufficient hormones.
4. Phenylketonuria (PKU): The body cannot break down the amino acid phenylalanine.
Nutritional Deficiency Diseases
Definition: Nutritional deficiency diseases occur due to inadequate intake or absorption of essential nutrients.
Types and Examples:
1. Scurvy: Caused by a vitamin C deficiency, leading to bleeding gums and joint pain.
2. Rickets: Caused by a vitamin D deficiency, weakening children’s bones.
3. Anemia: Often caused by iron deficiency, leading to fatigue and weakness.
4. Pellagra: Caused by a deficiency of niacin (vitamin B3), leading to diarrhea, dermatitis, and dementia.
Chronic Diseases
**Definition**: Chronic Human diseases are long-lasting conditions that often progress slowly and can be controlled but not cured.
Types and Examples:

2. Parkinson’s Disease: Affects movement, causing tremors and stiffness.
3. Epilepsy: A disorder characterized by recurrent seizures.
4. Migraine: Severe headaches often accompanied by nausea and sensitivity to light.
