What happens if pancreatitis is not treated?

Pancreatitis is inflammation of the pancreas. An acute episode may become severe, with persistent abdominal pain, repeated vomiting, dehydration and an inflammatory response that affects other organs. If inflammation continues or returns, the pancreas can develop lasting damage. This may interfere with digestion and the body’s ability to regulate blood sugar.

Common causes include gallstones and alcohol-related disease, but medicines, high blood fats and other conditions can also be involved. Finding the cause matters because treating the trigger can reduce further injury.

Severe or ongoing upper abdominal pain, especially with vomiting, needs same-day medical assessment. A GP or emergency clinician may examine you, arrange blood tests and use imaging such as an [Abdominal Ultrasound](/treatments/diagnostics-and-screening/abdominal-ultrasound/) when gallstones are suspected. Treatment may include fluids, pain relief, nutrition support and care for the underlying cause. Avoid alcohol until a clinician has assessed the illness.

Tell the clinician about medicines, alcohol use, previous gallstones and the timing of symptoms. Do not rely on home treatment if pain is escalating or fluids will not stay down.

Go to urgent care for severe abdominal pain, repeated vomiting, faintness, confusion, fever, yellowing of the skin or eyes, or difficulty breathing. These signs can accompany dehydration, infection or more severe inflammation. Call emergency services if you become faint, confused or seriously short of breath.

What may have triggered the pancreatitis? Do I need hospital monitoring or imaging? How should I manage food and fluids during recovery? Should I be assessed for gallstones or alcohol-related illness? What symptoms mean I should return urgently?
