Gallstones affect millions of people worldwide, often causing pain, digestive issues, and sometimes serious complications. Many seek non-surgical options to manage or eliminate gallstones, and one common question is whether Ursodeoxycholic Acid (UDCA), known by brand names like Ursofalk, can dissolve these stones effectively. This article explores how UDCA works, its effectiveness, limitations, and what patients should consider when exploring this treatment.

What Are Gallstones and Why Do They Form?
Gallstones are hardened deposits that form in the gallbladder, a small organ beneath the liver that stores bile. Bile helps digest fats, but when its components become imbalanced, solid particles can form. These stones vary in size and composition, mainly cholesterol or pigment stones.
Common causes of gallstones include:
Excess cholesterol in bile
Insufficient bile salts to dissolve cholesterol
Poor gallbladder emptying
Obesity, diet, and genetics
Gallstones can remain silent or cause symptoms like sharp abdominal pain, nausea, and digestive discomfort.
How Does Ursodeoxycholic Acid Work?
Ursodeoxycholic Acid is a naturally occurring bile acid that helps reduce cholesterol concentration in bile. It works by:
Decreasing cholesterol secretion from the liver into bile
Increasing bile acid secretion, which helps dissolve cholesterol
Improving bile flow and reducing gallbladder inflammation
By altering bile composition, UDCA may gradually dissolve cholesterol-based gallstones over time.
Effectiveness of Ursodeoxycholic Acid in Dissolving Gallstones
UDCA is primarily effective for small, cholesterol-rich gallstones in patients with functioning gallbladders. Research shows:
Dissolution rates vary but can reach 30-60% after 6 to 12 months of treatment
Stones smaller than 15 mm respond better
Pigment stones or calcified stones do not dissolve with UDCA
Gallbladder must be able to contract and empty properly for treatment to work
Who Is a Good Candidate for UDCA Treatment?
Doctors typically recommend UDCA for patients who:
Have small cholesterol gallstones without calcification
Experience mild or no symptoms
Are not suitable for surgery due to other health issues
Prefer to avoid surgery and want to try medication first
Patients with large stones, multiple stones, or gallbladder inflammation usually require surgical removal.
How Is Ursodeoxycholic Acid Taken?
UDCA is taken orally, usually in capsule form. Dosage depends on body weight but often ranges from 8 to 10 mg per kilogram per day, divided into two or three doses.
Treatment duration is long-term, often 6 months to 2 years, with regular monitoring through ultrasound to check stone size.
Potential Side Effects and Risks
UDCA is generally well tolerated, but some patients may experience:
Diarrhea or mild gastrointestinal discomfort
Allergic reactions (rare)
Liver enzyme changes (monitored by doctors)
It is important to follow medical advice and report any side effects promptly.
Alternatives to Ursodeoxycholic Acid
When UDCA is not suitable or effective, other options include:
Surgery (Cholecystectomy): Removal of the gallbladder is the most common and definitive treatment.
Extracorporeal Shock Wave Lithotripsy (ESWL): Uses sound waves to break stones but is rarely used.
Diet and Lifestyle Changes: Reducing fatty foods and maintaining healthy weight can prevent stone formation but do not dissolve existing stones.
Practical Tips for Patients Considering UDCA
Get a thorough diagnosis including ultrasound to confirm stone type and size.
Discuss with your doctor if UDCA is appropriate for your condition. Reimbursement for UDCA varies from country to country. For example, UDCA is not approved for the treatment of gallstones in Australia. Depending on the dose, it may cost several hundred dollars (AUD) per month if purchased privately.
Be patient: dissolution takes months or years.
Maintain follow-up appointments to monitor progress.
Report any new or worsening symptoms immediately.
Summary
Ursodeoxycholic Acid can dissolve certain types of gallstones, especially small cholesterol stones, but it is not a universal solution. Its success depends on stone size, composition, and gallbladder function. While it offers a non-surgical option for some, many patients will still require surgery for complete relief. If you have gallstones, consult a healthcare professional to determine the best treatment for your situation.
