Heartburn, also known as acid reflux, is a common condition where your stomach acid backs up into your esophagus, causing a burning sensation in your chest.

While heartburn can be caused by certain types of food, lifestyle factors, and medications, it can also be a symptom of an underlying health condition. Here are eight diseases that can cause heartburn, and what symptoms to look out for:.

1. GERD (Gastroesophageal Reflux Disease)

GERD is a chronic digestive disorder where stomach acid flows back into the esophagus, causing irritation and inflammation. Common symptoms include:.

Heartburn
Regurgitation of acid or food
Difficulty swallowing
Chest pain
Belching

2. Hiatal Hernia

A hiatal hernia occurs when the upper part of the stomach pushes through an opening in the diaphragm, and into the chest. This can weaken the lower esophageal sphincter, and cause acid reflux. Symptoms of a hiatal hernia include:.

Heartburn
Chest pain
Difficulty swallowing
Belching
Shortness of breath

3. Peptic Ulcers

Peptic ulcers are sores that develop in the stomach lining or duodenum (the first part of the small intestine). These can be caused by a bacterial infection, or by medications like aspirin and ibuprofen. Symptoms of peptic ulcers include:.

Heartburn
Stomach pain
Nausea
Vomiting
Bloating

4. Esophagitis

Esophagitis is inflammation of the esophagus, often caused by GERD or infection. Symptoms of esophagitis include:.

Heartburn
Pain when swallowing
Difficulty swallowing
Nausea
Vomiting

5. Gastroparesis

Gastroparesis is a condition where the muscles in the stomach don’t work properly, causing food to move more slowly through the digestive system. This can cause nausea, vomiting, and acid reflux. Symptoms of gastroparesis include:.

Heartburn
Nausea
Vomiting
Abdominal pain
Bloating

6. Achalasia

Achalasia is a rare disorder where the muscles in the esophagus don’t work properly, making it difficult to swallow. This can cause food to back up into the throat, leading to heartburn and regurgitation. Symptoms of achalasia include:.

Heartburn
Difficulty swallowing
Chest pain
Regurgitation of food or liquid
Weight loss

7. Pancreatitis

Pancreatitis is inflammation of the pancreas, which can cause digestive problems and a range of other symptoms. It can be caused by alcohol consumption, gallstones, or certain medications. Symptoms of pancreatitis include:.

Heartburn
Upper abdominal pain
Nausea and vomiting
Fever
Rapid pulse

8. Anxiety

Anxiety can cause a range of physical symptoms, including heartburn and acid reflux. When you’re anxious, your body releases stress hormones like cortisol and adrenaline, which can affect digestion and lead to digestive discomfort.

Symptoms of anxiety-related heartburn include:.

Heartburn
Indigestion
Nausea
Stomach pain or cramping
Loss of appetite

If you experience frequent heartburn, it’s important to see a doctor to rule out any underlying health conditions. Keep track of your symptoms, and make note of any triggers (like certain foods or stress) that seem to make your symptoms worse.

With the right diagnosis and treatment, you can manage your heartburn and reduce your risk of complications.
