Insulin Resistance and Weight Gain: Early Signs

Introduction

• When cells in your muscles, fat, and liver don’t react to insulin properly, you have insulin resistance. Another name for this is reduced insulin sensitivity. Insulin is necessary for both maintaining life and controlling blood sugar (glucose) levels.
• Did you know that your pancreas may need to generate more insulin in order to maintain normal blood sugar levels when your cells become less sensitive to insulin’s signals over time? When cells in your muscles, fat, and liver react poorly to insulin and are unable to use blood glucose as fuel efficiently, you have insulin resistance. Your pancreas makes up for it by making more insulin, but eventually this system breaks down, and your blood sugar levels rise.
• Complex metabolic changes cause the disease to develop gradually. Initially, your pancreas produces more insulin to keep blood glucose levels within normal ranges. While fasting glucose levels stay normal, this compensatory hyperinsulinemia can last for years. Blood glucose levels eventually rise, first after meals and then during fasting periods, as the pancreas is unable to maintain this elevated output.
• Blood sugar regulation is more difficult than it first appears. Diabetes is a complicated and sometimes fatal condition that requires more than just avoiding specific foods. Sadly, many people ignore its early warning signs, which, if ignored, can lead to major problems.
• According to the American Diabetes Association, over 39 million Americans have diabetes, and 8.7 million of them go untreated. Additionally, according to the CDC, one in three Americans has prediabetes, which is defined as blood sugar levels that are higher than usual but not high enough to be categorized as Type 2 Diabetes.
• Diabetes affects mental and emotional well-being in addition to physical health. Preventing or controlling the condition can be greatly aided by early detection of the symptoms and proactive lifestyle modifications. You can take charge of your health and lower your chance of long-term issues with the correct tools and assistance.

It’s critical and potentially life-saving to understand the silent signs of diabetes. The following are some typical indicators of diabetes:

Insulin resistance and weight gain: early signs you shouldn’t ignore

Diabetes symptoms are frequently modest or readily mistaken for other conditions. But since these symptoms point to altered blood sugar regulation, they should never be disregarded.

Fatigue or Constant Tiredness

Constantly feeling exhausted for no apparent cause could be a sign of an issue with the body’s sugar balance.

Prediabetes patients may experience persistent fatigue for the following reasons:

• Insulin Resistance: When cells become less sensitive to insulin, it becomes more difficult for the hormone to carry glucose molecules to the cells so they can produce energy.
• Decreased Insulin Production: When the body has insulin resistance, the pancreas may not be able to produce enough insulin. This could make it more difficult for cells to absorb glucose and use it to produce energy.
• Impaired Glucose Utilization: The body has more glucose than usual, particularly following a glucose load, as a result of insulin resistance and decreased insulin synthesis.
• Inadequate Sleep: Impaired glucose levels cause inadequate sleep, which may also be the cause of persistent fatigue.

People with prediabetes may experience persistent exhaustion, which affects their focus, productivity, and general quality of life.

For example, even after drinking coffee and getting eight hours of sleep, you still feel exhausted by midday. There may be more to this persistent fatigue than just stress.

Blurred Vision

• Vision distortion may result from the lens swelling due to high blood sugar. Additionally, this disease may damage the blood vessels in the eyes, resulting in fluid leakage, tissue separation, and the formation of new blood vessels, all of which can impair vision.
• Intermittent blurriness in one or both eyes may be a sign of prediabetes and a higher risk of developing diabetes.

For example, it’s worthwhile to have your blood sugar checked if you have trouble reading traffic signs or the screen of your phone, and your vision fluctuates.

Slow-Healing Cuts and Frequent Infections

High blood sugar increases the risk of infection and slows the healing of wounds. This includes increased infections, such as those of the skin, gums, or urinary tract, as well as delayed healing of small wounds and bruises.

An example: Recurring yeast infections or a little kitchen cut that takes weeks to heal could be your body’s way of warning you about high blood sugar.

Dark Patches on the Skin (Acanthosis Nigricans)

A skin condition called acanthosis nigricans causes thick, dark patches of skin to appear in the body’s creases and folds, particularly in the knees, elbows, armpits, and neck. One of the primary indicators of prediabetes is insulin resistance, which is commonly associated with it.

Example: It may be a sign of insulin sensitivity issues if you see these patches forming and they don’t go away with exfoliation or treatments.

Increased Thirst and Frequent Urination

Urine is one of the body’s natural responses to elevated blood sugar. Dehydration and extreme thirst follow from increased urine. These symptoms frequently coexist.

For example, if you frequently require water or wake up throughout the night to urinate, these could be early indicators of prediabetes.

Unexplained Weight Gain or Weight Loss

Insulin resistance increases lipogenesis and inhibits the use of glucose for energy. Because of this, those who are impacted frequently have weight issues, which can show up as abdominal obesity or the inability to lose weight even with dietary restriction and exercise.

For example, even with a healthy diet and regular exercise, you continue to gain weight or are unable to lose it.

Tingling or Numbness in Hands or Feet

Diabetes patients frequently experience nerve damage, which may occur before diabetes. Neuropathy from increased hyperglycemia may be indicated by prickling, insensitivity, or burning in the hands and feet.

For example, you shouldn’t ignore the tingling sensation in your feet or numb fingers you wake up with after sitting.

Increased Hunger or Cravings for Sugary Foods

You will always feel hungry even after meals and want to eat sweet or starchy foods if your body is having trouble using insulin.

Example: if you eat a big dinner and then seek a cookie an hour later, this could be related to blood glucose fluctuations.

Hearing Loss

Due to damage to tiny blood arteries and nerves, hearing loss is twice as prevalent in diabetics. It’s worth investigating if you experience a sudden change in your hearing.

Bleeding Gums

Red, swollen, and bleeding gums can result from bacterial development, which is encouraged by high blood sugar. See both a dentist and a physician if blood is visible on your toothbrush.

Perspiration Issues

Diabetes may be indicated by excessive or nonexistent perspiration, even when at rest. Both extremes should be examined with a healthcare professional because they are concerning.

Dry Mouth

Persistent dry mouth caused by high blood sugar might result in ulcers and discomfort. This is another indication of possible diabetes, along with bleeding gums and yeast infections.
