Introduction
In general, long-term consumption of lutein may be harmful to the body. Its adverse effects mainly include affecting sleep quality, skin abnormalities, gastrointestinal discomfort, damaging the liver and kidneys, and promoting stone formation. If any discomfort occurs, it is recommended to seek symptomatic treatment under a doctor's guidance. The specific analysis is as follows: long-term intake of lutein may have various negative impacts on the body.
Generally, long-term consumption of lutein may be harmful to the body, with potential adverse effects including impaired sleep quality, skin abnormalities, gastrointestinal discomfort, liver and kidney damage, and the formation of calculi (stones). If any discomfort occurs, it is recommended to seek medical guidance for symptomatic treatment. The specific analysis is as follows:
1. Impaired Sleep Quality
Lutein is an antioxidant that helps prevent damage caused by free radicals and may help prevent myopia. However, long-term use might affect the central nervous system, thereby impairing sleep quality and even causing insomnia. Lutein should be taken in moderation, and intake before bedtime should be avoided to prevent sleep disturbances.
2. Skin Abnormalities
Lutein tablets are yellow in color, and after entering the body, a portion may be converted into carotene. Prolonged excessive intake of lutein may lead to yellowing of the skin. Skin yellowing may be accompanied by mucocutaneous damage. Skin changes should be closely monitored during lutein use, and if abnormalities occur, medication should be stopped immediately and medical attention sought.
3. Gastrointestinal Discomfort
Lutein is an acidic substance; excessive intake may irritate the gastric mucosa, causing symptoms such as acid reflux and heartburn. Long-term, high-dose use may lead to gastric mucosal damage and even mild gastric ulcers. Lutein should be taken in moderation and not on an empty stomach to reduce irritation to the gastric mucosa.
4. Liver and Kidney Damage
When taken long-term and in large amounts as a medication, lutein can accumulate in the body, increasing the burden on the liver and kidneys and affecting circulation and metabolism of bodily fluids and blood. Symptoms such as dry mouth, bitter taste, and vomiting may also occur. Severe cases may lead to impaired liver and kidney function. Lutein should be taken under medical supervision, and liver and kidney function should be monitored regularly.
5. Formation of Calculi (Stones)
Concurrent use of lutein with sulfonamide drugs may increase the risk of kidney stones. Symptoms such as back pain and hematuria (blood in urine) may also occur. If other medications are required during lutein therapy, consult a physician to avoid potential drug interactions.
Long-term use of lutein may have multiple adverse effects on the body. Therefore, when taking lutein, it is important to use it in moderation, avoid excessive intake, and follow medical advice and guidance. Additionally, if any adverse symptoms occur, prompt medical attention should be sought, and the physician should be informed about the patient's medication history.
