Question

Uraemia is the occurrence of
A. Blood in urine
B. Excess of urea in the blood
C. Excess of sugar in the blood
D. Deficiency of sugar

Answer 1

Every nutrient is required in the body in an optimum amount. The excess and deficiency can cause the body to suffer from a disease. The macronutrients and micronutrients are required in the desired quantities. Their deficiencies can lead to fatal diseases.

Complete answer:
Urea is the waste from our body including uric acid and other toxic substances.
Blood is the red coloured fluid in our body which transports the oxygen and other vitals throughout the body.
Sugar is the carbohydrates which are broken down in the body to gain the energy.
Option A: Blood in urine: this condition is called hematuria. It is a serious disorder. This occurs due to problems in the kidneys or Urinary tract.
Option B: Excess of urea in the blood: The presence of uric acid or urea in blood Is called uremia. The whole waste of the body gets mixed in the blood. This usually occurs when the kidneys fail to do the filtration. It is a chronic disease.
Option C: Excess of sugar in blood: Hyperglycaemia is this condition when there is an increase in sugar levels in the blood. The body cant make insulin so it undergoes this disease. This is normally called diabetes.
Option D: Deficiency of sugar: Hypoglycemia is the other condition when the glucose levels in the blood are low. The glucose is required by the body to work so the body becomes very weak in this condition.

So the answer is option B: Excess of urea in the blood.

Note: Uremic syndrome is a serious disease of kidney failure. The building up of the kidney waste in the blood causes uremia. Kidney transplant becomes necessary in this condition when both the kidneys fail otherwise the person cannot stay longer.
