From Ulcers to Jaundice: 10 Questions to Test Your Gut Knowledge

 We often take our digestion for granted until something goes wrong. Whether it's a stomach ache, heartburn, or something more serious, our digestive system is sensitive!

Here are 10 Multiple Choice Questions (MCQs) to test how much you know about the disorders of the human digestive system. Useful for biology students, nursing aspirants, or anyone who wants to be health-conscious!

The Quiz

Q1. A patient’s eyes and skin have turned yellow. The doctor says this is due to the accumulation of bilirubin. What is this condition called?

A. Anemia

B. Jaundice

C. Scurvy

D. Diabetes

Answer: B (Jaundice)

Why? Jaundice happens when the liver malfunctions and cannot process bile pigments properly. This causes bilirubin (a yellow pigment) to build up in the blood, turning the skin and eyes yellow.

Q2. What is the main danger associated with severe Diarrhea?

A. Weight gain

B. High blood pressure

C. Dehydration

D. Increased appetite

Answer: C (Dehydration)

Why? In diarrhea, the body loses excessive water and electrolytes because the intestines stop absorbing them. This rapid loss of fluid (Dehydration) is actually more dangerous than the infection itself!

Q3. Which part of the brain controls the "Vomit Reflex"?

A. Cerebrum

B. Cerebellum

C. Medulla Oblongata

D. Hypothalamus

Answer: C (Medulla Oblongata)

Why? The "Vomit Center" is located in the Medulla (the lower part of the brainstem). It sends the signal to your stomach muscles to forcibly eject the food.

Q4. If a person suffers from "Constipation," what is happening in their Large Intestine?

A. It is absorbing too much water

B. It is not absorbing enough water

C. It is moving too fast

D. It is bleeding

Answer: A (It is absorbing too much water)

Why? When waste stays in the colon for too long, the colon sucks out too much water from it. This makes the stool dry, hard, and difficult to pass.

Q5. A burning sensation in the chest caused by stomach acid flowing back up into the food pipe is known as:

A. GERD (Acid Reflux)

B. Jaundice

C. Appendicitis

D. Cholera

Answer: A (GERD)

Why? This stands for Gastroesophageal Reflux Disease. It happens when the valve (sphincter) between the stomach and food pipe doesn't close tight enough, letting acid splash upward.

Q6. What is the primary cause of most Peptic (Stomach) Ulcers?

A. Eating too much spicy food

B. Bacterial infection (H. pylori)

C. Drinking cold water

D. Sleeping after eating

Answer: B (Bacterial infection - H. pylori)

Why? While spicy food can irritate an ulcer, the root cause is usually a bacteria called Helicobacter pylori or long-term use of painkillers, which damage the stomach's protective mucus layer.

Q7. "Indigestion" (Dyspepsia) is often caused by:

A. Proper chewing

B. Drinking water

C. Anxiety and Overeating

D. Sleeping 8 hours

Answer: C (Anxiety and Overeating)

Why? Indigestion isn't a disease itself but a sign that the stomach is struggling. Eating too fast, stress (anxiety), or inadequate enzyme secretion prevents food from breaking down properly.

Q8. Which organ is removed in a "Cholecystectomy" if it has stones?

A. Kidney

B. Liver

C. Gallbladder

D. Pancreas

Answer: C (Gallbladder)

Why? If bile hardens into stones (Gallstones) and blocks the ducts, the Gallbladder is often surgically removed. Don't worry, you can live without it!

Q9. If someone is "Lactose Intolerant," what are they missing?

A. Stomach Acid

B. The enzyme Lactase

C. Bile

D. Insulin

Answer: B (The enzyme Lactase)

Why? Lactose is the sugar found in milk. To digest it, you need an enzyme called Lactase. Without it, milk ferments in the gut, causing gas and bloating.

Q10. Appendicitis is the inflammation of the Appendix. Where is this organ located?

A. Top left of the stomach

B. Junction of Small and Large Intestine

C. Inside the Liver

D. At the end of the Rectum

Answer: B (Junction of Small and Large Intestine)

Why? The appendix is a small, finger-like tube attached to the Cecum (the start of the large intestine). If it gets blocked and infected, it can burst, which is a medical emergency.
