atrophy, a decrease in the size of a body part, cell, organ, or other tissue. The term implies that the atrophied part was of size normal for the individual, considering age and circumstance, prior to the diminution. In the atrophy of an organ or body part, there may be a reduction in the number or the size of the component cells, or in both.
Types of atrophy: 1. Glandular Atrophy. 2. Vaginal Atrophy. 3. Skeletal Muscle Atrophy. 4. Spinal Muscular Atrophy. 5. Multiple System Atrophy.

7. Injuries, such as a torn rotator cuff or broken bones.
8. Malnutrition.
9. Spinal cord or peripheral nerve injuries.
10. Stroke.
11. Long-term corticosteroid therapy.
12. Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, affects nerve cells that control voluntary muscle movement.
13. Dermatomyositis, causes muscle weakness and skin rash.
14. Guillain-Barré syndrome, an autoimmune condition that leads to nerve inflammation and muscle weakness.
15. Multiple sclerosis, an autoimmune condition in which the body destroys the protective coverings of nerves.
16. Muscular dystrophy, an inherited condition that causes muscle weakness.
17. Neuropathy, damage to a nerve or nerve group, resulting in loss of sensation or function.
18. Osteoarthritis, causes reduced motion in the joints.
19. Polio, a viral disease affecting muscle tissue that can lead to paralysis.
20. Polymyositis, an inflammatory disease.
21. Rheumatoid arthritis, a chronic inflammatory autoimmune condition that affects the joints.
22. Spinal muscular atrophy, a hereditary condition causing arm and leg muscles to waste away

1. Definition: Atrophy refers to the decrease in the size of a body part, cell, organ, or other tissue while hypertrophy refers to the enlargement of an organ or tissue from the increase in the size of its cells. 2.

1. Definition:
Atrophy refers to the decrease in the size of a body part, cell, organ, or other tissue while hypertrophy refers to the enlargement of an organ or tissue from the increase in the size of its cells.
2. Cause:
Moreover, atrophy occurs when organs or tissues are not used at all while hypertrophy occurs due to excess work.
3. Results in:
While atrophy results in a decrease in the size of the organ, hypertrophy results in an increase in the size of the organ.
4. Physiological Importance:
Senile atrophy, the atrophy in the thymus after puberty, and atrophy in ovaries and breasts during menopause are the physiological conditions of atrophy while the muscles of bodybuilders and the uterus in pregnant mothers are the physiological conditions of hypertrophy.
5. Pathological Importance
Chronic malnutrition and other chronic diseases cause atrophy, while hypertrophy can be either adaptive or compensatory.
6. Conclusion
See lessAtrophy is the condition of decreasing the size of an organ or tissue when they are not used for a long time. Further, malnutrition, chronic diseases, and aging are the causes of atrophy. On the other hand, hypertrophy is the condition of increasing the size of an organ or tissue due to excess work. Generally, this is by increasing cell volume. As an example, muscle hypertrophy occurs in bodybuilders. Therefore, the main difference between atrophy and hypertrophy is the type of change in organs and tissues and its causes.
