Jardiance (empagliflozin) has become a widely prescribed medication for managing type 2 diabetes and certain heart and kidney conditions, but many patients notice an unexpected side effect along the way: changes on the scale. So, does Jardiance cause weight loss, and if so, how does it actually happen? Here’s what’s worth understanding.
What Jardiance Is and How It Works
Jardiance belongs to a class of medications known as SGLT2 inhibitors (sodium-glucose cotransporter-2 inhibitors). It works by blocking the reabsorption of glucose in the kidneys, causing excess glucose to be excreted through urine rather than being absorbed back into the bloodstream. This mechanism helps lower blood sugar levels in people with type 2 diabetes and has also been shown to provide benefits for certain heart failure and chronic kidney disease patients, which is why it’s prescribed for these conditions as well.
The Connection Between Jardiance and Weight Loss
Yes, weight loss is a commonly observed effect in many patients taking Jardiance, and it’s directly tied to how the medication works. Since Jardiance causes the body to excrete glucose through urine instead of storing or using it, this represents a loss of calories that would otherwise have been retained by the body. Over time, this calorie loss can contribute to modest weight reduction.
Additionally, the increased urination caused by excreting extra glucose can result in some initial fluid loss as well, which may contribute to early, more noticeable weight changes, separate from actual fat loss.
How Much Weight Loss Is Typical?
Clinical studies on SGLT2 inhibitors like Jardiance have generally shown modest weight loss, often in the range of about 2 to 3 kilograms (roughly 4 to 6 pounds) over several months of use, though individual results vary considerably based on starting weight, diet, activity level, and other individual factors. This is generally considered a secondary benefit rather than the primary purpose of the medication, since Jardiance is specifically approved and prescribed for blood sugar control and certain cardiovascular and kidney-related benefits, not as a standalone weight loss treatment.
Why the Weight Loss Happens in Two Phases
Many patients notice an initial, sometimes more rapid period of weight loss in the first few weeks of starting Jardiance, largely attributed to fluid loss from increased urination. After this initial adjustment period, weight loss tends to level off into a slower, more gradual pattern, primarily related to the ongoing calorie loss from glucose excretion, rather than continued fluid loss.
Is Jardiance Approved as a Weight Loss Medication?
No, Jardiance is not FDA-approved specifically as a weight loss medication. It’s approved for managing type 2 diabetes, reducing cardiovascular risk in certain heart failure patients, and slowing the progression of certain chronic kidney disease cases. Any weight loss experienced while taking Jardiance is considered an associated effect of the medication’s mechanism, not its primary intended use.
This distinction matters because doctors don’t typically prescribe Jardiance to patients solely seeking weight loss without an underlying medical reason, such as type 2 diabetes, heart failure, or chronic kidney disease.
Potential Side Effects to Be Aware Of
While weight loss may be viewed as a welcome side effect by some patients, it’s important to be aware of other potential side effects associated with Jardiance, including:
- Increased urination and possible dehydration
- Urinary tract infections
- Genital yeast infections, due to increased glucose in urine
- Rarely, a serious condition called diabetic ketoacidosis, even in patients with normal or near-normal blood sugar levels
- Low blood pressure, particularly in patients also taking blood pressure medications or diuretics
Because of these potential side effects, Jardiance should only be used under the guidance and monitoring of a healthcare provider.
What This Means for Patients
If you’re prescribed Jardiance for diabetes, heart failure, or kidney disease, experiencing some degree of weight loss is a fairly common and generally well-documented effect of the medication. However, it shouldn’t be relied upon as a primary weight management strategy, and any significant or unexpected weight changes should be discussed with your doctor to ensure they align with your overall treatment goals and health status.
Final Thoughts
Yes, Jardiance can cause weight loss, primarily due to its mechanism of removing excess glucose, and the calories associated with it, through urine. While this effect is well-documented and often appreciated by patients managing type 2 diabetes, it’s considered a secondary benefit of the medication rather than its primary purpose, and any weight changes should be monitored alongside your doctor as part of your overall treatment plan.
