2. Common Medical Causes of Nausea

Several medical conditions can trigger nausea. Identifying the underlying cause is crucial for effective treatment. Here are some common medical reasons why you might feel nauseous:

2.1. Digestive Disorders

Digestive disorders frequently contribute to nausea. These conditions can disrupt the normal functioning of the gastrointestinal tract, leading to various symptoms, including nausea.

2.1.1. Irritable Bowel Syndrome (IBS)

IBS is a chronic condition that affects the large intestine. It can cause abdominal pain, bloating, gas, diarrhea, and constipation. Nausea is also a common symptom, often triggered by certain foods or stress.

Symptoms: Abdominal pain, bloating, gas, diarrhea, constipation, and nausea.
Triggers: Stress, certain foods (e.g., dairy, gluten), hormonal changes.
Management: Dietary modifications, stress management techniques, medications (e.g., antispasmodics, anti-diarrheals).

2.1.2. Gastroparesis

Gastroparesis is a condition in which the stomach empties too slowly. This can cause nausea, vomiting, abdominal pain, and a feeling of fullness after eating only a small amount of food.

Symptoms: Nausea, vomiting, abdominal pain, feeling full quickly, bloating.
Causes: Diabetes, nerve damage, infections, certain medications.
Management: Dietary changes (e.g., small, frequent meals), medications (e.g., prokinetics to speed up stomach emptying).

2.1.3. Acid Reflux (GERD)

GERD occurs when stomach acid frequently flows back into the esophagus. This can cause heartburn, regurgitation, and nausea.

Symptoms: Heartburn, regurgitation, nausea, chest pain, difficulty swallowing.
Triggers: Fatty foods, caffeine, alcohol, smoking.
Management: Lifestyle changes (e.g., avoiding trigger foods, elevating the head of the bed), medications (e.g., antacids, H2 blockers, proton pump inhibitors).

2.2. Infections

Infections, both bacterial and viral, can cause nausea. The body’s immune response to these infections can trigger nausea and vomiting.

2.2.1. Gastroenteritis (Stomach Flu)

Gastroenteritis, often referred to as the stomach flu, is an infection of the digestive system. It can cause nausea, vomiting, diarrhea, and abdominal cramps.

Symptoms: Nausea, vomiting, diarrhea, abdominal cramps, fever.
Causes: Viruses (e.g., norovirus, rotavirus), bacteria (e.g., Salmonella, E. coli).
Management: Rest, hydration, bland diet (e.g., BRAT diet: bananas, rice, applesauce, toast).

2.2.2. Food Poisoning

Food poisoning occurs when you consume food contaminated with bacteria, viruses, or parasites. It can cause nausea, vomiting, diarrhea, and abdominal pain.

Symptoms: Nausea, vomiting, diarrhea, abdominal pain, fever.
Causes: Contaminated food (e.g., raw or undercooked meat, unpasteurized dairy products).
Management: Rest, hydration, avoid solid foods until symptoms subside.

2.3. Migraines and Headaches

Migraines and severe headaches can often be accompanied by nausea. The neurological mechanisms underlying these conditions can trigger nausea as a related symptom.

2.3.1. Migraines

Migraines are severe headaches that can cause throbbing pain, sensitivity to light and sound, and nausea.

Symptoms: Throbbing headache, sensitivity to light and sound, nausea, vomiting, visual disturbances (aura).

Triggers: Alcohol, smoking, strong odors.
