Iodine And Laxatives: A Safe Mix?

Iodine is an essential mineral for the human body and is commonly found in seafood, dairy products, grains, and eggs. It is also added to table salt to prevent iodine deficiency. However, there are no sources that discuss whether it is safe to mix iodine with a laxative saline solution.

Iodine's antibacterial properties

Iodine is a cornerstone antibacterial application in hospitals and is often used before surgical procedures. It is a highly effective bactericidal agent, with a broad antimicrobial spectrum that includes Gram-positive and Gram-negative bacteria, fungi, and protozoa. Iodine's bactericidal activity is rapid, with studies showing that it can kill bacteria within 15 to 60 seconds of exposure.

Iodine's mechanism of action involves penetrating bacterial cell walls and membranes, interfering with DNA synthesis, and binding to proteins within the cell. This disrupts the cell's function and leads to cell death. Iodine's reactivity with a wide range of cellular components may be why bacteria have not developed resistance to it.

Iodine's effectiveness as an antibacterial agent is influenced by its concentration and the presence of other substances. Lower concentrations of iodine solutions may be more effective due to the higher proportion of free iodine available. However, the presence of organic substances like blood, pus, and fat can reduce iodine's antibacterial activity.

Iodine has been shown to be effective in preventing and treating a range of infections, including surgical site infections, conjunctivitis, corneal ulcers, and infectious diseases. It is also useful in decolonization procedures to reduce the risk of infection by pathogens like methicillin-resistant Staphylococcus aureus (MRSA).

Overall, iodine's unique chemical properties and broad-spectrum antimicrobial activity make it a valuable tool in infection control and the prevention of bacterial and microbial flora.

Iodine deficiency

Iodine is an essential trace mineral that is commonly found in seafood, dairy products, grains, and eggs. It is used by the thyroid gland to produce thyroid hormones, which play a crucial role in regulating metabolism, tissue repair, growth, and development. Iodine deficiency occurs when there is an inadequate amount of iodine in the body, typically due to insufficient iodine intake in the diet.

Symptoms of Iodine Deficiency

• Swelling in the neck (goitre) due to an enlarged thyroid gland
• Unexpected weight gain
• Fatigue and weakness
• Dry skin
• Feeling colder than usual
• Changes in heart rate, such as an abnormally slow heartbeat
• Learning and memory difficulties
• Heavy or irregular periods
• Miscarriages, stillbirths, and premature births in pregnant women
• Intellectual disability and stunted growth in unborn babies and young children

Risk Factors

Certain individuals are at a higher risk of developing iodine deficiency, including:

• Pregnant or breastfeeding women: They have increased iodine requirements to meet the needs of their growing baby.
• Vegans and vegetarians: One study found that 25% of vegetarians and 80% of vegans had iodine deficiency, compared to 9% of those on mixed diets.
• Individuals in certain geographical areas: This includes regions where there are low levels of iodine in the soil, such as South Asia, Southeast Asia, New Zealand, Europe, the Middle East, Africa, Latin America, and parts of Europe.
• Individuals who do not consume iodized salt: Iodized salt is a common way to increase iodine intake and prevent deficiency.

Treatment and Prevention

To prevent iodine deficiency, it is important to ensure adequate iodine intake through a balanced diet that includes iodine-rich foods or the use of iodized salt. The recommended daily intake of iodine for healthy adults is 150 mcg per day, while pregnant and breastfeeding women require higher amounts (220 mcg and 290 mcg, respectively).

Iodine supplements

Iodine is an essential trace mineral that is commonly found in seafood, dairy products, grains, and eggs. It is also added to table salt in many countries to help prevent iodine deficiency.

The thyroid gland uses iodine to produce thyroid hormones, which aid in tissue repair, regulate metabolism, and promote proper growth and development. Thyroid hormones also play a direct role in controlling body temperature, blood pressure, and heart rate.

Iodine deficiency is a common and preventable health problem worldwide, affecting more than 1.5 billion people. It can cause a range of symptoms, including swelling in the neck (goiter), hair loss, fatigue, weight gain, dry skin, and increased sensitivity to cold. Iodine deficiency may also cause severe problems in children and pregnant women, including brain damage and impaired mental development.

However, taking high doses of iodine for long periods can change the way the thyroid gland works and lead to adverse effects. Excess iodine intake can increase the risk of thyroid dysfunction, especially in fetuses, newborns, the elderly, and those with pre-existing thyroid conditions. Therefore, it is important to follow the recommended dosage for iodine supplements and not exceed the safe upper limit of 1,100 micrograms per day for adults.

Iodine toxicity

Iodine is an essential micronutrient that plays a crucial role in metabolism. It is required to produce thyroid hormones, which regulate growth, metabolism, and several other bodily functions, especially during fetal and neonatal brain development. While iodine deficiency is a well-known issue, the consequences of iodine excess are not often highlighted.

Iodine is not produced by the human body and must be obtained from external sources such as food, dietary supplements, medications, and iodinated contrast media. The recommended dietary allowance varies: 150 μg/d for adults, 220 to 250 μg/d for pregnant women, and 250 to 290 μg/d for breastfeeding women. Ingesting over 1.1 mg/d of iodine may lead to acute or chronic toxicity.

The clinical features of iodine toxicity from oral ingestion can range from mild to severe. Mild symptoms include gastrointestinal upset, nausea, vomiting, and diarrhea. More severe manifestations include delirium, confusion, lethargy, and shock. The condition rarely results in death.

If you suspect iodine toxicity or poisoning, it is crucial to seek immediate medical assistance. Do not induce vomiting unless instructed to do so by a medical professional. Provide the affected individual with milk or cornstarch/flour mixed with water. Continue to administer milk every 15 minutes as long as the person can swallow without difficulty.

Iodine in food

Iodine is an essential mineral that your body needs to function properly. It is a trace mineral commonly found in seafood, dairy products, grains, and eggs. The thyroid gland uses iodine to produce thyroid hormones, which aid in tissue repair, regulate metabolism, and promote proper growth and development.

The recommended daily intake (RDI) of iodine is 150 mcg per day for most adults. For pregnant women, the requirement is 220 mcg, and for lactating women, it is 290 mcg. Iodine deficiency can lead to swelling of the thyroid gland, known as a goiter, and hypothyroidism, resulting in fatigue, muscle weakness, and weight gain.

• Seaweed: A 10-gram serving of dried nori seaweed contains up to 232 mcg of iodine.
• Cod: A three-ounce serving of baked cod provides 158 mcg of iodine.
• Nonfat Milk: An eight-ounce serving of nonfat cow's milk contains 85 mcg of iodine.
• Greek Yogurt: Greek yogurt has a higher concentration of iodine, with up to 116 mcg per eight ounces.
• Oysters: Three ounces of cooked oysters can provide up to 93 mcg of iodine.
• Eggs: A single hard-boiled egg provides about 26 mcg of iodine.
• Enriched Bread: A slice of white bread made with an iodate dough conditioner can contain up to 185 mcg of iodine.
• Liver: A three-ounce serving of beef liver provides 14 mcg of iodine, along with other essential vitamins and nutrients.
