Bleeding of gums, falling of teeth, fragile bones and delayed wound healing occur due to the deficiency of which one of the following vitamins?
Vitamin C
The question describes a set of symptoms including bleeding of gums, falling of teeth, fragile bones, and delayed wound healing. These specific symptoms are characteristic of a condition known as scurvy, which is caused by a deficiency of Vitamin C.
Vitamin C, also known as ascorbic acid, is an essential nutrient that plays a crucial role in several bodily functions. One of its most important roles is in the synthesis of collagen. Collagen is a protein that serves as a major building block for connective tissues throughout the body, including those found in:
Collagen is vital for maintaining the structural integrity and strength of these tissues. It is also essential for the process of wound healing, as it forms the matrix for new tissue growth.
When there is a deficiency of Vitamin C, the body cannot produce enough collagen. This lack of collagen leads to the weakening of connective tissues, resulting in the symptoms described:
Let's briefly consider why the other options do not typically present with this particular combination of symptoms:
Based on the clear link between Vitamin C's role in collagen synthesis and the described symptoms of weakened connective tissues, the deficiency of Vitamin C is the cause.
| Symptom | Link to Vitamin C Deficiency (Scurvy) |
|---|---|
| Bleeding Gums | Weakened connective tissue in gums due to poor collagen synthesis. |
| Falling Teeth | Compromised structural support for teeth due to collagen deficiency in gums and jaw. |
| Fragile Bones | Reduced collagen matrix in bones makes them brittle. |
| Delayed Wound Healing | Collagen is essential for tissue repair and scar formation. |
The collection of symptoms including bleeding gums, falling teeth, fragile bones, and delayed wound healing is a hallmark of scurvy, a disease caused by insufficient intake of Vitamin C. Therefore, the deficiency of Vitamin C is responsible for these health issues.
| Vitamin | Key Role | Deficiency Disease/Symptoms |
|---|---|---|
| Vitamin C (Ascorbic Acid) | Collagen synthesis, antioxidant, immune function | Scurvy (bleeding gums, fatigue, poor wound healing, fragile bones, joint pain) |
| Vitamin K | Blood clotting | Excessive bleeding (hemorrhage) |
| Vitamin D (Calciferol) | Calcium & phosphate absorption, bone health | Rickets (children), Osteomalacia (adults) - soft bones, deformities |
| Vitamin B1 (Thiamine) | Energy metabolism, nerve function | Beriberi (nerve damage, muscle weakness, cardiovascular issues) |
| Vitamin B2 (Riboflavin) | Energy metabolism | Ariboflavinosis (cracked lips, skin inflammation, eye problems) |
| Vitamin B3 (Niacin) | Energy metabolism, nervous system | Pellagra (Dermatitis, Diarrhea, Dementia, Death) |
| Vitamin B9 (Folate) | DNA synthesis, cell growth | Megaloblastic anemia, neural tube defects in newborns |
| Vitamin B12 (Cobalamin) | Nerve function, DNA synthesis, red blood cell formation | Megaloblastic anemia, neurological problems |
Scurvy is a historical disease often associated with sailors on long voyages with limited access to fresh fruits and vegetables. It is relatively rare today in developed countries due to widespread availability of Vitamin C-rich foods and fortified products. However, certain groups are still at risk, including:
Good sources of Vitamin C include citrus fruits, berries, tomatoes, peppers, broccoli, and leafy greens. Cooking can reduce the Vitamin C content of foods, so consuming some raw sources is beneficial.
The recommended daily allowance (RDA) for Vitamin C varies by age, sex, and life stage (e.g., pregnancy, lactation). Ensuring adequate intake through diet or supplements is key to preventing scurvy and maintaining overall health.
