Kwashiorkor disease develops due to

  1. Malnutrition.

  2. Over eating.

  3. Catalysis.

  4. Mutation.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Kwashiorkor is malnutrition produced by a severely inadequate amount of protein in the diet. It is also called as protein malnutrition.
  • Symptoms include texture, fatigue, diarrhea, loss of muscle mass, failure to grow or gain weight, edema (swelling) of the ankles, feet, and belly, the damaged immune system, which can lead to more frequent and severe infections, irritability.
  • Hence Kwashiorkor disease develops due to Malnutrition.
  • So, the correct answer is 'Malnutrition'.
Multiple choice biology nutrition and diet effect on general health diseases caused by changes in lifestyle diet, drugs and disease

Nutritional disease will appear due to

  1. Obesity

  2. Unbalanced diet

  3. Mental disease

  4. Diabetes
Reveal answer Fill a bubble to check yourself
B Correct answer

Inadequate protein intake leads to Kwashiorkor. The subsequent edema is most closely related to inadequate synthesis of which protein

  1. Gamma globulin

  2. Glucagon

  3. Insulin

  4. Albumin
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Kwashiorkor is caused by severe protein deficiency. Albumin is the primary plasma protein responsible for maintaining oncotic pressure; its reduced synthesis leads to fluid leakage into tissues, causing edema.
