Insulin resistance is a condition where your body’s cells don’t respond appropriately to the hormone insulin, which plays a crucial role in regulating blood sugar levels. If left untreated, insulin resistance can lead to type 2 diabetes and other health complications. 

Recognizing the signs of insulin resistance is essential for taking proactive steps to manage your health. For some help, below are five typical indicators your body might display when experiencing signs of insulin resistance.

Skin Changes

Our skin often serves as a mirror reflecting the state of our internal health, and among the particularly telling Signs of Insulin Resistance in Kids and adults is a skin condition known as acanthosis nigricans. 

It appears as dark, thickened patches of skin, typically in the folds and creases of the body. Common locations include the armpits, neck, back, and groin area. These patches often have a velvety texture and vary in size and intensity. 

So, what’s the connection between these skin changes and insulin resistance? Insulin resistance, characterized by impaired cellular response to insulin, leads to elevated insulin and glucose levels in the bloodstream. 

The surplus insulin can stimulate the growth of skin cells, particularly in areas with a high density of insulin receptors. As a result, these regions become more prone to developing acanthosis nigricans.

Increased Thirst

Insulin resistance fundamentally affects how your body manages glucose, the primary energy source. When your cells become less responsive to insulin, a hormone responsible for regulating blood sugar levels, the glucose in your bloodstream remains elevated. As a result, your kidneys kick into overdrive to eliminate this excess sugar from your body.

Here’s how it unfolds: High blood sugar levels trigger the kidneys to filter more blood and produce more urine to expel the surplus glucose. This increased urine production leads to dehydration, which, in turn, triggers your body’s thirst mechanism. You frequently reach for a glass of water or other beverages to quench your thirst.

At first, it might be easy to dismiss this increased thirst as simply needing to hydrate more. However, it should be a warning sign when it becomes a persistent and unexplained sensation. Your body attempts to compensate for elevated blood sugar levels and dehydration caused by insulin resistance.

Increased Hunger

With glucose unable to enter your cells effectively, your body perceives a lack of energy, even though there’s plenty of glucose circulating in your bloodstream. In response, your brain sends signals indicating hunger to encourage you to eat more, believing you need more fuel.

This increased hunger can feel overwhelming and persistent, leading you to consume more food or snacks frequently throughout the day. It’s important to note that this is not a simple case of overeating or emotional eating; your body attempts to compensate for the energy deficit caused by insulin resistance.

Ignoring persistent hunger can have serious consequences, as unmanaged insulin resistance can progress to type 2 diabetes and increase the risk of various complications, including cardiovascular problems and nerve damage. If you are constantly hungry despite eating adequately, it’s crucial to consult a healthcare professional to evaluate your blood sugar levels and overall health.

Tingling Sensation on the Bottom of the Feet

High glucose levels in the bloodstream can lead to glycation, where excess sugar molecules attach to nerve fibers. It disrupts the normal functioning of nerves and can lead to abnormal sensations like tingling, burning, or numbness, especially in the extremities, such as the bottom of the feet.

The tingling sensation indicates that your nerves are struggling to function correctly due to the impact of insulin resistance. It’s a warning sign that high blood sugar levels compromise your body’s delicate neural network.

While addressing the tingling is essential for relieving discomfort, it’s equally crucial to address the root cause: insulin resistance. Taking proactive steps to manage your blood sugar levels through lifestyle changes, such as adopting a balanced and low-glycemic diet, engaging in regular physical activity, and maintaining a healthy weight, can help prevent further nerve damage.

Slow-Healing Cuts and Sores

The body’s ability to heal itself is a marvel of biological engineering. When you sustain an injury, whether a cut, bruise, or sore, a complex series of events is set in motion to repair the damaged tissue. However, when insulin resistance comes into play, this remarkable healing process can be significantly hindered, leading to delayed wound recovery.

Here’s why: Insulin resistance can affect blood flow to the injured area. Blood brings essential nutrients and oxygen that help wounds heal. When you have insulin resistance, blood circulation can be less efficient, making it harder for your body to repair itself.

If you’ve noticed that your cuts or sores take a long time to heal, it’s a sign that something might be wrong. Other factors can also cause slow healing, like age or other health issues. Insulin resistance could be a factor, especially if you’ve noticed signs like increased thirst or skin changes.


Understanding the signs of insulin resistance is vital for taking control of your health early on. If you’ve noticed any of these symptoms or have a hunch that you might have insulin resistance, it’s time to take action. Remember, your well-being is in your hands, and early intervention is the key to a healthier future.
