What are the tiny white spots on the nails? Top functional medicine doc says it could be a warning sign

Ever noticed small white spots on your fingernails? Though those tiny white spots might seem harmless, they could be your body’s way of sounding an alarm. Dr. Shirley Koeh, a leading functional medicine doctor based in Kuala Lumpur, has explained the reason behind those white spots. “Do you notice all these tiny white spots on your nails? And it just happens for no reason. This is your body trying to warn you,” the doctor said, in a video shared on Instagram.

What are those white spots

White spots on your nails are common and are generally harmless. However, if those are multiplying and lingering longer, it could be an issue.

The white spots or streaks on your fingernails or toenails could be leukonychia. According to Dr. Koeh, these marks can reflect underlying health problems that may have been developing for weeks or months. Nails grow slowly, so these white spots or any changes are signs of your body’s health over time. While occasional spots might result from minor trauma, persistent white spots or those that linger longer could be leukonychia.

Nutrient deficiency

Dr. Koeh pointed out that leukonychia could happen due to nutrient deficiencies. “They are often a sign of zinc deficiency, selenium deficiency, or even low protein,” the doctor said.

A lack of these nutrients can weaken nails and cause white spots to appear. Zinc supports tissue repair, while selenium acts as an antioxidant, and protein is a building block for nails. Deficiencies in any of these nutrients may stem from poor diet, malabsorption, or chronic health conditions.

Arsenic exposure

Dr. Koeh also added that it could indicate exposure to arsenic. “And here is the part most people miss. This can be a sign of arsenic exposure. One of the most common sources is actually the rice. She pointed out that rice can absorb arsenic from contaminated soil, water, or pesticides used in farming. Over time, regular consumption may lead to low-level arsenic buildup in the body, which can manifest as white spots on nails, fatigue, or more severe health issues if left unaddressed.

It is important to understand that your nails are like a window into your health. So, do not ignore what they’re telling you. Recognizing the problem at an early stage can prevent further health issues. If the white spots on nails stay longer or appear very often, it is important to seek professional guidance. Taking action now could make all the difference.
