Insulin deficiency in the body causes

Last Updated: 26 Jun 2026

This question examines a fundamental concept of human anatomy, physiology, health, nutrition, disease, or body regulation that frequently appears in SSC CGL General Science. The human body works through coordinated organ systems. Questions may also test blood components, vitamins, glands, sense organs, communicable diseases, and deficiency disorders. A familiar word is not automatically correct; qualifiers such as “largest,” “primary,” “deficiency,” “secreted by,” “carries,” or “controls” determine the answer. Restate the question in your own words, predict the answer before checking the options, and confirm that the explanation and correct-option field both point to Diabetes mellitus.

Correct Answer: Diabetes mellitusYour Answer: C

Explanation

There are two main types: Type 1 (autoimmune destruction of beta cells — insulin-dependent) and Type 2 (insulin resistance — lifestyle-related, most common). It has absolutely NO relation to insulin deficiency. Dwarfism — Dwarfism is caused by deficiency of Growth Hormone (GH) from the pituitary gland during childhood. It is NOT related to insulin. Anaemia — Anaemia is caused by iron deficiency (most common), or Vitamin B12/folate deficiency. It is NOT caused by insulin deficiency. 📝 Important Note: Hormone deficiency diseases — Insulin: Diabetes mellitus; Growth Hormone (GH): Dwarfism (children); Thyroxine: Cretinism (children), Myxoedema (adults); ADH: Diabetes insipidus. Glucose tolerance test is used to diagnose diabetes.

Important Notes

this record is Diabetes mellitus, corresponding to option C. The answer field, correct index, and both explanations must remain aligned.
Read the complete stem and identify the exact demand: organ, gland, hormone, cell, tissue, nutrient, enzyme, pathogen, vector, deficiency disease, body fluid, or physiological function.
Learn nutrition facts as nutrient–source–function–deficiency pairs. Vitamins and minerals can have several roles, but SSC questions usually ask the best-known primary association.
Goitre, Dwarfism, Anaemia are eliminated here because none satisfies the precise requirement of the stem. Practising the reason for each rejection is more reliable than memorising only the correct choice.
Numerical biological facts often vary with age, sex, body size, and reference range. Use the standard approximate value expected in school-level competitive examinations and retain its unit.

FAQ

SSC CGL Human Body FAQs

Common questions and clear answers for this topic.

Which body systems are most important for SSC CGL preparation?

The digestive, circulatory, nervous, and skeletal systems appear most frequently, along with sensory organs and basic endocrine functions.

How many bones are there in the human body, and is this commonly asked?

Yes, the human body has 206 bones, and questions about the largest, smallest, and total bone count appear fairly often.

What kind of blood-related questions come up in SSC CGL?

Questions usually cover blood group compatibility, the role of platelets in clotting, and basic facts about blood pressure and heart function.

Do I need detailed biochemistry knowledge for the human body section?

No, most questions focus on what each organ does and why, rather than the detailed biochemical processes behind it.

How can I retain human body facts more effectively for the exam?

Linking facts to real-life observations, like why pulse is checked at the wrist, makes them easier to recall than memorizing textbook lines.
