Linzess and Weight Loss: Does It Work and Is It Safe?

By Norma Ector · · Updated

Contents

Are you struggling to lose weight and wondering whether Linzess could help? Linzess (linaclotide) is a prescription medication used to treat irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC).

Linzess is not a weight-loss drug. It works on bowel movements, not body fat, and taking it to lose weight can cause diarrhea and dehydration.

In this article, we’ll explain how Linzess and weight loss are connected, why using it for weight loss is a bad idea, and which safe and effective methods can help you reach your goals.

What is Linzess?

Linzess is the brand name for linaclotide, a prescription capsule for IBS-C in adults and for certain types of constipation in adults and in children 6 and older.

According to MedlinePlus linaclotide drug information, it is taken once a day on an empty stomach, at least 30 minutes before a meal, at about the same time each day.

Follow your doctor’s instructions for your dose. Children under 2 should never take linaclotide because of the risk of serious dehydration.

Linzess and Weight Loss: What’s the Connection?

Weight loss is not one of Linzess’s uses, and MedlinePlus does not list it as a side effect. Some people notice the scale drop when they start the drug, but that reflects emptier bowels and fluid shifts, not fat loss.

How does Linzess speed up the digestive process?

Linzess increases the secretion of fluid in the intestines, which helps to soften stool and make bowel movements easier. This can lead to more frequent bowel movements.

How does Linzess reduce water retention?

It doesn’t, in the way this claim suggests. Linzess pulls fluid into the intestines and out with the stool. Losing fluid this way is not the same as losing body fat, and too much of it causes dehydration.

However, it’s important to note that weight loss is not an expected outcome of taking Linzess. Any short-term change on the scale returns as soon as you eat and drink normally. Use Linzess only for the bowel condition your doctor prescribed it for.

Can Linzess Cause Weight Loss?

Not in a meaningful way. Linzess can make you lose stool and water weight, but it does not burn fat or reduce calories absorbed in a way that leads to lasting weight loss.

Is it safe to use Linzess for weight loss purposes?

No. Linzess is not approved or recommended for weight loss. Taking it without a bowel condition, or taking more than prescribed, raises the risk of diarrhea and dehydration.

What are the potential risks of using Linzess for weight loss?

Misusing Linzess can cause severe diarrhea, dehydration and electrolyte imbalances. Signs of dehydration include extreme thirst, dry mouth or skin, sunken eyes and a fast heartbeat; stop the drug and call your doctor if they appear.

Using laxative-type drugs to control weight can also be a sign of an eating disorder. Using Linzess for weight loss will not work over time. It’s important to approach weight loss in a safe and sustainable way, with the guidance of a healthcare professional.

Using Linzess for Weight Loss: What You Need to Know

If you take Linzess for IBS-C or chronic constipation and notice changes in your weight, keep these points in mind:

1. Follow your doctor’s instructions carefully

Take Linzess exactly as prescribed, once a day on an empty stomach at least 30 minutes before a meal. Do not raise the dose to try to lose weight.

2. Don’t expect immediate results

Linzess will not work for weight loss purposes. Lasting weight loss comes from changes to diet and activity, not from a constipation medication.

3. Be aware of potential side effects

Common side effects include diarrhea, stomach pain, bloating, gas and headache. Call your doctor for severe stomach pain, bloody or black stools, or dizziness or fainting.

4. Use Linzess only as directed

Using Linzess without a medical reason, or in higher doses than prescribed, can lead to dehydration. Use it only for the condition your healthcare professional is treating.

5. Monitor your progress and report any changes

Report unexplained weight loss, ongoing diarrhea or signs of dehydration to your doctor. Unintended weight loss can have other causes that should be checked.

Other Options for Weight Loss

Linzess is not a weight-loss option. There are many safe and effective ways to lose weight, including:

1. Eating a healthy diet

Eating a healthy and balanced diet can help you achieve sustainable weight loss. This includes consuming plenty of fruits, vegetables, whole grains, and lean protein, and limiting processed foods, sugar, and saturated fat.

2. Exercising regularly

Regular exercise can help you lose weight and maintain a healthy weight over time. The CDC’s adult physical activity guidelines call for at least 150 minutes of moderate-intensity activity a week, plus 2 days of muscle strengthening.

3. Getting enough sleep

Getting enough sleep is important for maintaining a healthy weight. Lack of sleep can disrupt the hormones that regulate appetite, making it more difficult to control food intake.

4. Reducing stress

Stress can also affect eating habits and make it more difficult to lose weight. Finding healthy ways to manage stress, such as through exercise, meditation, or therapy, can help support weight loss efforts.

5. Working with a healthcare provider or registered dietitian

Working with a healthcare provider or registered dietitian can help you develop a personalized weight loss plan that takes into account your individual needs and medical history. They can also provide support and accountability throughout your weight loss journey.

For people with obesity, doctors can also prescribe FDA-approved weight-loss medications, which require medical supervision.

Conclusion

Linzess is not an option for weight loss. It treats IBS-C and chronic constipation, and misusing it can cause diarrhea and dehydration. If you are struggling with weight loss, there are many safe and effective options available, including healthy eating, exercise, stress management, and working with a healthcare provider or registered dietitian.

Sustainable weight loss takes time and patience. By building healthy habits and seeking guidance from healthcare professionals, you can achieve your weight loss goals and improve your overall health and well-being.
