Starting keto can feel like a total lifestyle upgrade—increased energy, fat loss, fewer cravings. But there’s one less glamorous side effect that many people don’t talk about: constipation.

If you’re feeling backed up on your low-carb journey, you’re not alone. This guide breaks down why constipation happens on keto, how to relieve it quickly, and how to prevent it long term while staying in ketosis.

Why Does Keto Cause Constipation?

Switching to a ketogenic diet often leads to changes in digestive habits, especially during the first few weeks. Here are the common causes:

1. Gut flora shift: A change in your diet affects your gut microbiome, which can disrupt digestion.

2. Low fiber intake: Reducing carbs often means eating fewer fruits, grains, and legumes, which are key fiber sources.

3. Dehydration: Keto has a natural diuretic effect, leading to more fluid loss and potential dehydration.

4. Electrolyte imbalance: Sodium, magnesium, and potassium levels can drop, affecting muscle contractions in the digestive tract.

Symptoms of Keto-Related Constipation

• Infrequent bowel movements (fewer than 3 per week)

• Hard or dry stools

• Bloating or gas

• Straining during elimination

If symptoms persist beyond 1–2 weeks or cause significant discomfort, consult a healthcare professional.

How to Avoid Constipation on Keto

1. Increasing Fiber Intake

Fiber isn’t just found in carb-heavy foods. There are plenty of keto-friendly, fiber-rich foods out there! These include non-starchy vegetables like broccoli, avocados, and leafy greens. Including these in your diet can improve your digestion while keeping you in ketosis.

2. Staying Hydrated

Water is critical, especially on keto. Not only does it prevent dehydration, but it also helps fiber do its job more effectively. So, remember to keep your water bottle close at all times.

3. Regular Exercise

Physical activity helps stimulate your intestines, improving bowel motility. A quick walk after meals or regular workouts can work wonders!

4. Magnesium Supplements

Magnesium is a natural laxative that can help alleviate constipation. Some people find taking a magnesium supplement beneficial. But, remember to consult your healthcare provider before starting any supplement regimen.

When to Seek Medical Help

1. Symptoms of Severe Constipation

While occasional constipation is normal, if it’s persistent and accompanied by symptoms like abdominal pain, bloody stool, or unexpected weight loss, it’s time to seek medical attention.

2. Chronic Constipation and Health Risks

Ignoring chronic constipation can lead to complications like hemorrhoids or rectal prolapse. So don’t hesitate to reach out to a healthcare professional if you’re concerned.
