Symptom 6. Muscle Weakness and Aches – A Misinterpreted Sign of Low Iodine
Muscle weakness and aches are another symptom that could indicate low iodine levels. This might seem surprising at first glance. After all, what does a mineral like iodine have to do with our muscles? But if you delve deeper into iodine’s role in muscle function, the connection becomes apparent.
Thyroid hormones, which need iodine for their production, play a crucial role in several bodily functions, including muscle control. They influence the metabolic activity of muscle tissues and ensure proper muscle function. They regulate the way muscles contract and relax, and even impact how muscles repair themselves after a workout.
When iodine levels are low, thyroid hormone production decreases, leading to hypothyroidism. This can disrupt muscle function, leading to symptoms such as muscle weakness, stiffness, aches, and sometimes even swelling.
It’s important to note that muscle weakness related to low iodine isn’t the same as simply feeling tired or worn out after physical exertion. Instead, it’s a constant feeling of weakness, making everyday tasks difficult.
You might find it hard to carry things you previously could, or you might struggle to climb stairs. Similarly, muscle aches associated with iodine deficiency aren’t just regular soreness after a workout. Instead, they’re persistent aches and pains that don’t seem to improve with rest. (6)
