Victoza (liraglutide) affects digestion, appetite regulation, hydration, and multiple organ systems. While many patients experience mild nausea, others develop severe, persistent, or permanent side effects, some requiring hospitalization or surgery. Common side effects of Victoza (liraglutide) include nausea, diarrhea, vomiting, decreased appetite, indigestion, and constipation. These gastrointestinal issues are most common when starting treatment and usually subside over time. Serious risks include gallbladder issues, kidney problems due to dehydration, thyroid tumors, and pancreatitis.
Victoza (liraglutide) is a GLP-1 receptor agonist. Most of its common side effects are gastrointestinal and tend to occur when starting the medication or increasing your dosage. These symptoms usually subside as your body adjusts. Victoza is utilized for the treatment of people 18+, and children over 10 years and above with improperly controlled type 2 diabetes mellitus as a supplement to exercise and diet. Victoza may be used as monotherapy when metformin is believed to be unworkeable as a result of intolerance or contraindications. Victoza can also be utilized- supplementing other prescription medication for the treatment of diabetes.
This page outlines Victoza side effects, from common reactions to serious complications, and explains when symptoms may indicate a medical emergency.
Victoza’s GLP-1 activity:
- slows gastric emptying
- alters intestinal motility
- suppresses appetite
- affects fluid balance
- changes vascular regulation
With daily dosing, these effects may become continuous.
Common Victoza Side Effects

Severe Gastrointestinal Side Effects
Persistent Vomiting & Inability to Eat

- dehydration
- repeated ER visits
Vomiting lasting more than a few days is not normal.
Motility Disorders & Bowel Shutdown
Victoza (liraglutide), a GLP-1 receptor agonist used for type 2 diabetes, acts by slowing gastric emptying and decreasing intestinal motility to regulate blood sugar, which can lead to severe gastrointestinal complications known as motility disorders or “bowel shutdown”. These complications include gastroparesis (stomach paralysis), ileus (intestinal blockage), and severe constipation, with studies showing a higher risk of intestinal obstruction in patients using these medications.
Reported conditions include:
- gastroparesis
- ileus
- severe constipation
- generalized GI dysmotility

- dehydration
- acute kidney injury
- worsening kidney disease
- dialysis in severe cases

Gallbladder Side Effects
Weight loss and altered digestion may increase the risk of:
- gallstones
- gallbladder attacks
- gallbladder inflammation
- gallbladder removal surgery

Pancreatitis Risk
Symptoms may include:
- severe upper abdominal pain
- pain radiating to the back
- vomiting
- hospitalization

Vision Side Effects & Blindness (NAION)
Reported vision problems include:
- sudden vision loss
- blurred or dim vision
- loss of peripheral vision
- NAION
NAION can cause permanent blindness.

Some Victoza users report symptoms that:
- continue months after stopping
- require permanent dietary restrictions
- interfere with work and daily life
- cause chronic disability
