by Many individuals experience a burning sensation on the soles of their feet, often describing it as intense heat or a feeling of being on fire. This discomfort can be perplexing and distressing, leading people to seek answers about its cause. This post aims to provide a clear and functional explanation, offering insights into how this issue can often be prevented.
The human body is designed to function in balance, with extremes being detrimental to its health. Glucose, derived from the food we consume, is the body’s primary source of fuel. Carbohydrates, such as bread, flour, rice, potatoes, and sweets, are readily converted into glucose. Proteins also convert to glucose, though in smaller amounts, while fats are processed into fatty acids that can be used as fuel. Glucose is essential for various bodily functions, including bone formation, brain repair, and cell regeneration.
Maintaining balanced glucose levels is crucial. When a person gains weight, it often indicates an excess of glucose in the body. Fat formation is a result of the combination of glucose and insulin. Consuming excessive carbohydrates leads to increased glucose production, prompting the pancreas to release insulin. This combination of glucose and insulin then leads to fat storage.
Excess glucose, beyond what is used for energy or stored as fat, undergoes fermentation, as all sugars do. When glucose levels consistently exceed 130 milligrams per deciliter, the fermentation process results in the production of lactic acid. Lactic acid is denser than water, causing it to gravitate downwards due to gravity. As it accumulates in the lower extremities, the acidic nature of lactic acid can cause a burning sensation in the feet.
This excess acid can also lead to dry, peeling skin on the soles of the feet, creating an environment conducive to fungal infections. Therefore, the burning sensation in the feet is often a direct consequence of excess glucose, stemming from a diet high in carbohydrates, which also contributes to obesity.
