Stomach Diseases

Stomach disorders can affect digestion and appetite, causing symptoms such as stomach pain, bloating, indigestion, nausea, vomiting, acidity, ulcers, and loss of appetite. If left untreated, some conditions may lead to serious digestive complications.

Stomach Diseases

There are various diseases of the stomach:

Loss of Appetite (Jou-ul-Baqar)

In this condition, the body needs food, but the stomach does not create the feeling of hunger. The desire to eat and drink decreases significantly.

Normally, when food reaches the stomach, the stomach walls stretch. In response, a gastric hormone is released that controls stomach movements and stimulates the gastric glands to produce gastric juice. This juice is highly acidic, with a pH ranging from 0.9 to 1.5, and contains pepsin, hydrochloric acid (HCl), intrinsic factor (required for the absorption of Vitamin B12), and various proteolytic enzymes that play an important role in digestion.

Any imbalance in these digestive secretions may result in loss of appetite.

Stomach Pain

There are three main forms:

1. First Type

The patient feels pain in the stomach along with:

  • Excess saliva

  • Nausea

  • Retching

  • Vomiting

  • Indigestion

  • Increased saliva production

Causes

  • Excessive use of phlegm-producing foods

  • Cholera

  • Indigestion

2. Second Type

Symptoms include:

  • Abdominal bloating

  • Rumbling sounds in the abdomen

  • Sour belching

  • Restlessness

  • Severe constipation

  • Colicky abdominal pain

Causes

  • Excessive use of sour foods

  • Frequent consumption of heavy and hard-to-digest foods

  • Eating without need

3. Third Type

Symptoms include:

  • Stomach pain

  • Excessive thirst

  • Yellow-colored vomiting

  • Burning during urination

  • Cramping during bowel movements

  • Anxiety and restlessness

  • Sleeplessness

  • Burning sensation in hands and feet

  • Yellowish skin complexion

Causes

  • Excessive use of hot and dry foods

Indigestion

In this condition, only the digestive function of the stomach is disturbed, while the structure of the stomach remains normal.

Three to four hours after eating, the patient may experience:

  • Stomach pain

  • Tightness

  • Heaviness

  • Restlessness

  • Nausea or vomiting

  • Constipation or diarrhea

  • Abdominal pain

  • Bad breath

  • Mild fever

  • Sour belching

  • Sour fluid rising into the mouth

Sometimes sediment appears in the urine, and occasionally albumin may be present in the urine.

If indigestion continues for a long period, appetite decreases significantly. The patient feels heaviness and mild pain in the upper stomach area, especially after meals. Gas accumulates in the abdomen, sour belching occurs, and alternating constipation and diarrhea may develop.

The face loses its glow, the body becomes weak, and the patient gradually loses weight. Fatigue, sluggishness, palpitations, stomach burning, throat irritation, mouth ulcers, and burning hands and feet may also occur.

Causes

  • Eating repeatedly before previous food is digested

  • Frequent consumption of bakery products

  • Excessive eating at restaurants

Hiccups (Fawaq)

A hiccup is a sudden involuntary movement that usually originates from a stomach-related disturbance. It occurs when the diaphragm and other breathing muscles contract suddenly. As air rushes into the voice box, the vocal cords react with a sudden jerk, producing the characteristic hiccup sound.

Causes

  • Accumulation of fluids in the upper part of the stomach

  • Excessive buildup of gas

  • Severe thirst

  • Dryness of the tongue

  • Excessive use of foods that produce irritating humors or secretions

Nausea, Retching, and Vomiting

A special center in the medulla of the brain is connected to the chemoreceptor trigger zone. When this center is stimulated, excessive saliva is produced. As the saliva enters the stomach, it causes stimulation and distension of the stomach.

At this stage, the opening of the food pipe near the mouth becomes relaxed, while the pyloric opening leading to the small intestine becomes tightly constricted. The stomach repeatedly contracts and relaxes. Since the pyloric outlet is blocked, the stomach contents are forced upward and expelled through the mouth, resulting in vomiting.

If the sensation of vomiting occurs but little or no material is expelled, it is called retching.

When the stomach becomes extremely weak, it develops an aversion to harmful substances and loses its normal activity. The person feels constantly uneasy and uncomfortable. This condition is called nausea.

Causes

  • Excessive consumption of cold and moist foods

  • Exposure to cold weather

  • Eating unnecessarily

  • Food poisoning

Pain at the Upper Opening of the Stomach (Cardiac End of the Stomach)

Nature has made this area highly sensitive because it plays an important role in creating the sensation of hunger. Even minor discomfort in this region can be felt intensely. Sometimes the patient may become faint and develop cold sweats.

Causes

  • Severe stress and anxiety

  • Excessive use of dry foods

Excessive Hunger (Jou-ul-Kalb)

In this condition, the appetite becomes abnormally strong. Even after eating, the person continues to feel hungry. Since such greed for food is commonly associated with dogs, it is traditionally called "Jou-ul-Kalb."

This is considered a false hunger rather than a true one. It is commonly seen in people with diabetes. It may also occur in children who have intestinal worms that consume part of their nutrition, leaving them constantly hungry.

Causes

  • Intestinal worms

  • Diabetes

  • Excessive use of sour foods

  • Pickles

  • Ketchup

  • Soft drinks

  • Chutneys and similar condiments

Bloating (Flatulence)

Flatulence refers to excessive gas in the digestive system. During eating, some air enters the intestines. Additional gas is produced when bacteria break down food. These gases include nitrogen, carbon dioxide, hydrogen, and methane.

When food is not digested properly, it ferments and produces gas inside the stomach and intestines.

This gas can cause abdominal pain. After eating, the abdomen may become increasingly swollen, and within two or three hours it may feel tight like a drum. Gas may not pass easily, causing heaviness, discomfort, and weakness.

Other symptoms include:

  • Abdominal pain

  • Sour or burning belching

  • Excess saliva

  • Frequent spitting

  • Heartburn

  • Rapid heartbeat

  • Dizziness

  • Shortness of breath

Infants who drink milk often become very uncomfortable in this condition and may become restless. Stool may become frothy and foul-smelling.

Causes

  • Frequent use of bakery products

  • Overeating

  • Lying down immediately after meals

  • Consumption of hard-to-digest foods

Belching

Belching is the release of gas from the stomach or food pipe, either naturally or intentionally. It commonly occurs after meals when the stomach becomes full and the lower esophageal sphincter relaxes.

Belching is a normal process because it releases swallowed air. However, excessive swallowing of air can cause bloating and abdominal pain.

This often happens when:

  • Too much food is eaten

  • Gas-producing foods are consumed excessively

People suffering from indigestion may also experience frequent belching along with:

  • Abdominal pain

  • Nausea

  • Retching

  • Vomiting

  • Heartburn

Some people belch frequently because they breathe through their mouth due to a blocked nose.

Persistent excessive belching and excessive gas in the stomach and intestines may also be associated with depression. Such patients often experience continuous anxiety and restlessness.

Causes

  • Overeating

  • Mental stress

  • Indigestion

  • Nasal blockage

  • Depression

Vomiting of Blood (Hematemesis)

The patient may experience severe pain in the stomach area, often described as if being pierced by a knife or spear. Sometimes only a burning sensation is present.

Blood may be expelled with forceful vomiting or may appear in small amounts. It may be:

  • Thin or thick

  • Frothy

  • Mixed with food

  • Pure blood

The amount may range from small to very large, and severe bleeding can be life-threatening.

Causes

  • Stomach ulcer

  • Certain complications in hepatitis patients

  • Rupture of varicose veins in the stomach

  • Poisoning or toxic substances

  • Stomach cancer

  • Improper suppression of menstrual bleeding (traditional medical concept)

Gastritis (Inflammation of the Stomach)

When the stomach muscles become overstimulated, they contract excessively and may even go into spasms. At the same time, the stomach glands become less active and fail to produce sufficient digestive juices.

As a result:

  • Appetite decreases

  • Food remains in the stomach longer than normal

  • Gas and fermentation develop

  • Indigestion occurs

Other symptoms include:

  • Excessive thirst

  • Sour belching

  • Burning sensation in the stomach

  • Constipation

  • Burning in hands and feet

  • Reduced urine output

  • Dark-colored urine

As the condition progresses, the mouth may fill with saliva, and the patient may experience:

  • Mild stomach pain after meals

  • Sour fluid rising into the mouth

  • Fatigue

  • Mental discomfort

Eating and drinking often worsen the symptoms, causing the patient to reduce food intake and become weak.

Long-standing untreated gastritis may lead to infection with Helicobacter pylori, resulting in severe upper abdominal pain, nausea, retching, vomiting, and highly acidic vomit.

Gastric Swelling (Edema/Severe Inflammation of the Stomach)

If gastritis continues for a long time or is not treated properly, it may develop into swelling of the stomach. In this condition, the inner mucous lining of the stomach becomes red and swollen.

Early Symptoms

  • Heaviness in the stomach

  • Restlessness

  • Feeling of suffocation or discomfort

  • Nausea

  • Excessive saliva

  • Bitter fluid in the mouth

  • Frequent belching

  • Coated tongue

  • Loss of appetite

  • Increased thirst

  • Constipation

  • Reduced and dark-red urine

  • Headache

  • Mild fever

In children, the inflammation may spread toward the intestines, causing diarrhea and severe abdominal pain. In adults, constipation is more common.

If the inflammation spreads into the duodenum (the first part of the small intestine), the bile duct may become swollen, sometimes causing mild jaundice after a day or two.

Severe Symptoms

When the swelling becomes severe, symptoms become more intense:

  • Fever up to 103°F

  • Dry, yellow-coated tongue

  • Mouth ulcers and sores

  • Swollen gums

  • Bad breath

  • Frequent nausea and vomiting

  • Vomiting of undigested food followed by mucus

  • Severe stomach burning

  • Extreme thirst

  • Complete loss of appetite

  • Abdominal bloating

  • Pain when pressure is applied to the upper stomach

  • Cramping abdominal pain

  • Poor sleep

  • Burning sensation in the palms and soles

  • Very little, dark-colored urine with heavy sediment

  • Dry skin

  • Pale complexion

  • Progressive weakness and weight loss

  • Sadness and lack of motivation

  • Rapid pulse

  • Loose stools before abdominal cramps

Causes

  • Eating spoiled food

  • Consuming rotten or stale meat

  • Chronic alcohol use

  • Poisoning and toxic substances

  • Chemical-based medications

Gastric Ulcer (Peptic Ulcer)

The inner lining of the stomach, called the mucosa, is covered by a protective mucus layer. This lining extends throughout the digestive tract and helps food move smoothly.

Special cells in the stomach produce:

  • Hydrochloric Acid (HCl) – helps break down food.

  • Pepsinogen – helps digest proteins.

The stomach is normally protected from its own acid by mucus-producing glands. However, when acid and digestive enzymes become excessive and the protective mucus layer becomes weak, the acid starts damaging the stomach lining.

Initially, this causes irritation and burning. Drinking fluids may temporarily reduce the burning sensation, but it often returns when the acid rises again.

If the condition continues:

  • Inflammation develops.

  • Pain becomes more severe.

  • The stomach lining may become ulcerated.

  • Bleeding may occur.

Early signs include black stools due to bleeding. In severe cases, vomiting blood may occur.

If left untreated, an ulcer can become a serious condition and may lead to further complications.

Symptoms of Gastric Ulcer

  • Burning in the stomach about 30 minutes after eating

  • Burning lasting 3–4 hours

  • Sharp, cutting pain as the condition worsens

  • Relief after food leaves the stomach

  • Excess gas and belching

  • Nausea and vomiting

  • Sour or bitter fluid rising into the mouth

  • Swelling near the stomach opening

  • Incomplete bowel movements

  • Intestinal inflammation

  • Bleeding gums

  • Dark or pale teeth

  • Persistent bad breath

  • Yellowish discoloration of the eyes

  • Dark circles under the eyes

  • Dull nails

  • Frequent bloating, gas, and constipation

  • Fatigue and weakness

  • Dizziness

  • Excessive hunger due to increased acidity

Some patients feel worse on an empty stomach and better after eating, while others become afraid to eat because food triggers pain and burning.

Causes

  1. Infection with Helicobacter pylori

  2. Excessive spicy restaurant food

  3. Bakery sweets and biscuits

  4. Frequent consumption of roasted meat

  5. Excessive use of acidic foods and drinks

  6. Irregular meal schedules

  7. Stress and tension

  8. Refined flour products such as samosas, pastries, and fried snacks

  9. Smoking, alcohol, betel nut products, and gutka

  10. Toxic substances

  11. Excessive tea and coffee consumption

  12. Long-term use of painkillers such as aspirin and similar medicines

Cholera

Cholera is a severe and potentially life-threatening acute disease. It is divided into two types:

1. Epidemic Cholera

In this form, Vibrio cholerae infects the small intestine and causes inflammation, resulting in repeated vomiting and diarrhea.

2. Non-Epidemic Cholera

This type is commonly seen during hot weather. People consume large amounts of cooling foods such as:

  • Cucumbers

  • Melons

  • Watermelons

According to the traditional explanation in the text, drinking excessive water immediately after such foods may weaken digestion and lead to vomiting and diarrhea.

Stages of Cholera

1. Early Stage

  • Abdominal pain

  • Vomiting and diarrhea

  • Initially stool contains waste material

  • Later stool resembles rice-water discharge

  • Vomiting follows a similar pattern

2. Progressive Stage

Symptoms become more severe:

  • Frequent vomiting and diarrhea

  • Muscle cramps in hands and feet

  • Headache

  • Abdominal pain

  • Intense thirst

  • Water is vomited immediately after drinking

  • Severe anxiety and restlessness

This stage may last 10–12 hours.

3. Critical Stage

Due to severe fluid loss:

  • Blood becomes thicker

  • Circulation slows

  • Body temperature falls

  • Extreme weakness develops

  • Cold sweating occurs

  • The body becomes cold

  • Breathing becomes difficult

  • The patient struggles to speak

  • Eyes appear sunken

  • Intense thirst continues

  • Bluish circles appear around the eyes

  • Pulse becomes weak and irregular

  • The face appears lifeless

Vomiting and diarrhea may stop at this stage. Many patients may die during this critical phase if treatment is not provided promptly.

4. Recovery Stage

If the patient survives the critical stage:

  • Vomiting stops

  • Body warmth returns

  • Pulse improves

  • Strength gradually returns

  • Appetite begins to recover

  • Facial appearance improves

  • Recovery slowly takes place

Causes

  • Excessive use of antacid medicines that reduce stomach acid

  • Conditions that weaken natural stomach acidity

  • In non-epidemic cholera, drinking water immediately after eating cucumber, watermelon, melon, and similar foods
