pancreas with nausea

Overview

The pancreas is a small organ behind your stomach that helps digest food and control blood sugar. When it becomes inflamed or irritated—a condition called pancreatitis—it can cause nausea, vomiting, and belly pain.

Pancreatitis is not extremely common, but it affects about 50 out of 100,000 people each year.

Anyone can get pancreatitis, but it's more common in adults, especially those who drink heavily or have gallstones.

Symptoms

Common symptoms

• Nausea and vomiting
• Severe pain in the upper belly that may go to the back
• Swollen or tender belly
• Fever
• Fast heartbeat
• Oily, foul-smelling stools (in chronic pancreatitis)

Causes

Main causes

• Gallstones blocking the pancreatic duct
• Heavy alcohol use
• High levels of fats (triglycerides) in the blood
• Certain medications (ask your doctor)
• Injury to the belly or surgery
• Infections
• High calcium levels

Risk factors

• Obesity
• Smoking
• Family history of pancreatitis
• Gallstones
• Heavy drinking
• Diabetes

When to see a doctor

See a doctor urgently if:

• Severe belly pain that does not go away
• High fever with belly pain
• Vomiting that prevents you from drinking fluids

Book a routine appointment if:

• Mild nausea and belly pain that come and go for several days
• Unexplained weight loss
• Oily stools

Diagnosis

Your doctor will take your history, examine your belly, and order blood tests to check for high levels of pancreatic enzymes. They may also order imaging tests to look at your pancreas.

Tests that may be done

• Blood tests (amylase and lipase levels)
• Ultrasound of the belly
• CT scan
• MRI or MRCP (special scan of the pancreas and bile ducts)
• Stool tests for fat

What to expect at your appointment

Your doctor may ask you to stay in hospital for a few days to get fluids and pain relief. Tests are done to find the cause. Most people improve within a week.

Treatment

Treatment depends on the cause and severity. The main goals are to rest the pancreas, manage pain, and treat the underlying cause.

Self-care at home

• Stop eating or drinking for a few hours to give the pancreas a rest (as advised by your doctor)
• Once allowed, start with clear liquids like water, broth, or apple juice
• Avoid alcohol and fatty foods
• Take pain relievers only as recommended by your doctor

Medical treatments

Doctors often start with IV fluids to prevent dehydration. Pain medications are given. If vomiting is severe, you may need a nasogastric tube (a tube through your nose to the stomach) to drain stomach contents. Antibiotics are sometimes used if there is an infection. Gallstones may be removed with an endoscopic procedure (ERCP).

When is surgery considered?

Surgery may be needed to remove the gallbladder if gallstones caused the pancreatitis. In severe cases, dead tissue may need to be removed from the pancreas.

Living with this condition

After an episode of pancreatitis, you may need to make long-term changes to protect your pancreas. This often includes a low-fat diet, no alcohol, and regular check-ups.

Lifestyle tips

• Avoid alcohol completely
• Eat small, low-fat meals
• Stop smoking
• Maintain a healthy weight
• Take enzyme supplements if prescribed

Diet and exercise

A dietitian can help you plan meals low in fat and high in nutrients. Gentle exercise like walking is usually fine, but avoid heavy lifting right after an episode.

Mental health and emotional wellbeing

Living with a chronic condition like pancreatitis can cause anxiety and depression. Talk to your doctor or a counselor if you feel overwhelmed.

Prevention

Not all cases can be prevented, but you can lower your risk by limiting alcohol, maintaining a healthy weight, and managing medical conditions like high triglycerides.

Complications

If left untreated

• Chronic pancreatitis with ongoing pain and digestive problems
• Diabetes
• Pseudo-cysts (fluid-filled sacs inside the pancreas)
• Infections
• Pancreatic cancer risk increases with chronic pancreatitis

Long-term outlook

With proper treatment and lifestyle changes, most people recover well from acute pancreatitis. Chronic pancreatitis can be managed, but it requires ongoing care. The outlook depends on the cause and how well you follow your treatment plan.
