What Happens if You Get Too Much Manganese?

Too much manganese can cause problems, especially with your brain and nervous system. One condition linked to high manganese levels is manganese-induced parkinsonism, which has symptoms similar to Parkinson’s disease. This includes tremors, difficulty moving, and memory issues.

Other health problems can occur too, such as:

• Skin Irritation: Manganese may cause skin reactions if you come into contact with it often.
• Breathing Issues: Breathing in manganese dust or fumes can lead to lung problems.
• Reproductive Health Issues: Too much manganese may affect your ability to reproduce.

Symptoms of Manganese Overexposure

If you get too much manganese, you might start to feel unwell. Some early signs include:

• Headaches
• Tiredness
• Weak muscles

As exposure continues, symptoms can worsen and may include:

• Nausea
• Vomiting
• Confusion or memory loss
• Severe cases can lead to seizures, coma, or even death

What Are the Long-Term Effects of Manganese Exposure?

Long-term exposure to manganese can lead to permanent damage to the brain and other organs. Some of the risks include:

• Parkinson’s Disease: Manganese-induced parkinsonism can lead to movement and memory problems over time.
• Neurodegenerative Diseases: Manganese exposure may increase the risk of diseases like Alzheimer’s.
• Organ Damage: It can cause harm to the liver, kidneys, and other organs.
