Introduction: The Saltwater Flush
A saltwater flush involves drinking a saline solution to induce a bowel movement and cleanse the colon. Proponents claim it helps with constipation or as part of a detox, although medical evidence for its effectiveness is limited. The flush works via osmosis, where the high salt concentration draws water into the intestines, causing a bowel movement. It's crucial to perform this procedure safely to avoid complications.
Why Iodized Salt Is Dangerous for a Saltwater Flush
Using iodized table salt for a saltwater flush is risky due to iodine overdose and the presence of additives. Iodized salt contains potassium iodide or potassium iodate, added to prevent iodine deficiency, which is beneficial in small dietary amounts. However, the large amounts needed for a flush can lead to iodine toxicity.
Iodine Overdose: The Risks
Excessive iodine intake can overwhelm the thyroid, causing severe health issues. The thyroid has the Wolff-Chaikoff effect to regulate hormone overproduction, but this can fail, especially in those with pre-existing conditions.
Symptoms of iodine overdose include:
- Metallic taste in the mouth
- Burning in the mouth and throat
- Fever and abdominal pain
- Nausea, vomiting, and diarrhea
- Weak pulse
- Confusion, delirium, or coma
These symptoms are concerning, and the amount of salt needed for the laxative effect far exceeds the safe daily iodine limit, making this an unnecessary risk.
Additives in Table Salt: The Problem
Table salt often contains anti-caking agents like sodium ferrocyanide or calcium silicate. While safe for normal use, these aren't meant for large internal consumption and can cause gastrointestinal distress.
Comparison: Iodized vs. Non-Iodized Salt in Flushes
| Feature | Iodized Salt (Table Salt) | Non-Iodized Salt (Sea/Himalayan) |
|---|---|---|
| Composition | Refined sodium chloride with added potassium iodide/iodate. | Unrefined sodium chloride with trace minerals. |
| Recommended Use | Dietary intake to prevent iodine deficiency. | Culinary purposes, canning, or saltwater flushes. |
| Additives | Contains anti-caking agents. | Typically additive-free. |
| Flush Safety | Unsafe due to iodine risk and additives. | Safe for a flush, if no health issues. |
| Taste | Processed or metallic taste. | Cleaner taste, better for flushes. |
Safer Alternative: The Non-Iodized Saltwater Flush
Use safe, non-iodized salt and follow a clear procedure. Warning: Consult a healthcare professional before attempting this, especially with high blood pressure, kidney issues, or chronic conditions.
Ingredients:
- 1 liter (4 cups) of warm, filtered water
- 2 teaspoons of non-iodized salt (Himalayan or sea salt)
- Optional: A squeeze of lemon juice
Instructions:
- Warm the water: Use warm water.
- Dissolve the salt: Dissolve the salt in water.
- Add lemon (optional): Add lemon juice if desired.
- Drink quickly: Consume the solution quickly on an empty stomach.
- Relax and wait: Stay near a bathroom for 1-2 hours.
Conclusion: Prioritize Safety
Using iodized salt for a saltwater flush can lead to severe health problems, especially iodine overdose. The additives in table salt make it unsuitable. Use pure, non-iodized salt like pink Himalayan or Celtic sea salt. Always consult a doctor before starting any cleanse, particularly if you have existing health issues. Safety and well-being should be the priority.

Safer Alternatives for Digestive Regularity
Staying Hydrated: Drink plain water and eat water-rich foods to help maintain digestive health.
High-Fiber Diet: Eat foods rich in fiber, such as whole grains, legumes, nuts, and seeds to regulate digestion.
Probiotic-Rich Foods: Consume fermented foods like yogurt and kimchi to add beneficial bacteria and promote a balanced gut microbiome.
Herbal Teas: Certain teas with psyllium or marshmallow root may gently aid digestion.
Regular Exercise: Physical activity stimulates intestinal muscles and promotes bowel function naturally.
Resistant Starches: Found in plant-based foods, they act like fiber and promote a healthy gut microflora, supporting colon health.
Listen to Your Body: Use the bathroom when needed to maintain a healthy digestive rhythm.
What to Do If You Accidentally Use Iodized Salt
Seek Medical Help: If you experience symptoms of iodine toxicity, seek emergency treatment immediately. Call 911 or your local emergency services.
Provide Details: Inform medical staff about the amount of iodized salt ingested, your weight, and any health conditions, especially thyroid or kidney issues.
Stay Calm: Minor cases of iodine poisoning usually don't cause lasting problems with prompt treatment.
Monitor Symptoms: Report any changes to the medical team. Do not induce vomiting unless directed by a healthcare provider.
Kosher Salt vs. Iodized Salt
Kosher salt is a non-iodized, coarse-grained salt, primarily sodium chloride. Unlike iodized salt, it has no added iodine and usually no anti-caking agents, making it a pure form of salt favored by many chefs.
Does Sea Salt Contain Enough Iodine to Be Dangerous?
No. Sea salt contains trace minerals, including iodine, but the concentration is too low to cause an iodine overdose during a flush. The iodine risk is specific to iodized salt.
Who Should Avoid a Saltwater Flush?
People with high blood pressure, kidney disease, or heart conditions should avoid a saltwater flush due to the sodium load. Pregnant or breastfeeding women and those with thyroid disorders should not do a saltwater flush without medical supervision.
Short-Term Side Effects of a Saltwater Flush
Common side effects, even with non-iodized salt, include bloating, nausea, vomiting, and stomach cramps. The flush can cause an electrolyte imbalance, leading to muscle cramps or headaches.
Can a Saltwater Flush Cause Dehydration?
Yes, a saltwater flush can cause dehydration if you don't hydrate properly after the flush. The flush draws water into the intestines, and the resulting bowel movements can cause fluid loss, requiring rehydration.
