ORLANDO, Fla. (Ivanhoe Newswire) — While it’s normal to lose 50 to 100 strands of hair daily, excessive shedding may signal an underlying issue. For those who have recently lost weight, diet and rapid weight reduction could be contributing factors to thinning hair.
Weight loss can have significant positive effects on health and self-esteem, but it can also bring an unwelcome side effect: hair loss.
Temporary Hair Loss After Rapid Weight Loss
According to registered dietitian nutritionist Kait Richardson, RDN, hair loss often follows a period of rapid weight loss, particularly after bariatric surgery or drastic dietary changes. This shedding typically begins three to four months after weight loss and tends to be temporary, lasting about six months. People might also notice changes in their nails, such as brittleness or thinning.
“If you’re experiencing hair loss, it’s important to first rule out other health conditions,” Richardson advises. “Getting your thyroid checked is a good first step to ensure that it isn’t the underlying cause of your thinning hair.”
The Impact of Surgery and Diet on Hair Growth
A study involving 112 women who underwent gastric sleeve surgery revealed that nearly 75% experienced hair loss afterward. Additionally, recent research published in the journal Cell indicates that both humans and animals following intermittent fasting diets showed slower hair growth.
Nutrient Deficiencies and Hair Health
Nutrient deficiencies are another common cause of hair loss after weight loss. “The key is to make sure you’re consuming a balanced diet with a wide variety of nutrients,” Richardson explains. Protein, zinc, iron, fatty acids, selenium, and Vitamin D are particularly important for maintaining healthy hair.
Richardson recommends consulting with a healthcare provider to determine if a nutrient deficiency is to blame. A simple blood test can help identify any deficiencies and guide dietary changes or supplementation.
Other Possible Causes of Hair Loss
While rapid weight loss is often a culprit, certain medications, stress, high fever, childbirth, and severe illness or infections can also trigger temporary hair loss. For example, medications like Ozempic, commonly used for weight loss, may lead to temporary hair shedding, but they do not directly cause baldness.
In some cases, hair loss can result from being in surgery for an extended period, especially if the head remains still for more than four hours. Hypotensive anesthesia, which lowers blood pressure, can also affect blood flow to hair follicles, potentially leading to hair loss.
Consulting a Doctor for Proper Diagnosis
If you’re experiencing significant hair loss following weight loss, it’s important to consult with a doctor. A simple blood test can reveal any underlying issues, and a tailored approach to nutrition and health can help restore hair growth. While hair loss is often a temporary effect, addressing the root cause can help prevent long-term damage to your hair and overall well-being.
