Why Recognizing High Blood Sugar Warning Signs Matters?
High blood sugar warning signs are your body’s way of alerting you to a dangerous situation. Whether you have diabetes or are at risk of developing it, being aware of these signals can be lifesaving. Ignoring these warnings can lead to serious health complications, including heart disease, kidney damage, and nerve problems.
As someone who has lived with type 2 diabetes for over a decade, I’ve experienced firsthand how crucial it is to pay attention to these warning signs. Let’s dive into the 10 key high blood sugar warning signs you should never ignore.
10 Key High Blood Sugar Warning Signs
1. Increased Thirst and Frequent Urination
One of the most common high blood sugar warning signs is an insatiable thirst coupled with frequent trips to the bathroom.
Why it happens: When your blood sugar is high, your kidneys work overtime to filter and absorb the excess glucose. When they can’t keep up, this excess glucose is excreted into your urine, dragging along fluids from your tissues. This makes you urinate more frequently and subsequently feel thirstier.
My experience: I remember constantly feeling parched, carrying a water bottle everywhere, and waking up multiple times at night to use the bathroom. It was disruptive and exhausting.
What to watch for:
- Drinking more water than usual without explanation
- Waking up at night to urinate
- Feeling thirsty even after drinking water
2. Fatigue and Weakness
Feeling unusually tired or weak, especially after meals, can be a significant indicator of high blood sugar.
Why it happens: When your body can’t properly use glucose for energy due to insulin resistance or lack of insulin, your cells become starved for energy, leading to fatigue.
My experience: Before my diagnosis, I felt like I was constantly dragging myself through the day. Even simple tasks felt overwhelming, and I needed naps frequently.
What to watch for:
- Feeling tired even after a full night’s sleep
- Experiencing sudden energy crashes, especially after carb-heavy meals
- Difficulty concentrating or feeling mentally foggy
3. Blurred Vision
Sudden changes in vision, particularly blurriness, can be a scary but important high blood sugar warning sign.
Why it happens: High blood sugar can cause the lens of your eye to swell, changing its shape and affecting your ability to focus.
My experience: I first noticed this when I was having trouble reading road signs while driving. It was alarming, but it improved once my blood sugar was under control.
What to watch for:
- Difficulty focusing on close objects
- Temporary vision changes
- Seeing halos around lights
4. Slow-Healing Wounds
If you notice cuts, scrapes, or other wounds taking longer than usual to heal, it could be a sign of high blood sugar.
Why it happens: elevated blood sugar can damage blood vessels and nerves, reducing blood flow and sensation in certain areas, particularly the feet. This slows down the healing process.
My experience: A minor cut on my foot took weeks to heal, which was unusual for me. This prompted me to check my blood sugar more regularly.
What to watch for:
- Cuts or scrapes that linger for weeks
- Wounds that seem to get worse instead of better
- Frequent infections in wounds
5. Recurrent Infections
Frequent infections, especially yeast infections or urinary tract infections, can be a sign of high blood sugar.
Why it happens: Excess sugar in your blood and tissues allows bacteria and yeast to thrive, making infections more likely.
My experience: I found myself getting more frequent urinary tract infections, which was unusual for me. This, combined with other symptoms, led to my diabetes diagnosis.
What to watch for:
- More frequent urinary tract infections
- Recurring yeast infections
- Skin infections that don’t clear up with usual treatment
6. Dry, Itchy Skin
Persistent dry, itchy skin can be more than just a nuisance—it can be one of the high blood sugar warning signs.
Why it happens: High blood sugar can lead to decreased circulation and nerve damage, affecting your skin’s ability to stay moisturized. Additionally, frequent urination can lead to dehydration, further drying out your skin.
My experience: I noticed my skin becoming increasingly dry and itchy, especially on my legs and feet. Moisturizer didn’t seem to help much until I got my blood sugar under control.
What to watch for:
- Persistently dry skin despite using moisturizers
- Itchy skin, especially on the lower legs
- Cracked or rough skin that doesn’t improve with typical treatments
7. Unexplained Weight Loss
While many people might welcome unexpected weight loss, it can be one of the more serious high blood sugar warning signs.
Why it happens: When your body can’t use glucose properly for energy, it starts burning fat and muscle for energy instead, leading to weight loss.
My experience: Despite eating more than usual, I lost about 15 pounds in a month without trying. It was confusing and concerning, prompting me to see my doctor.
What to watch for:
- Losing weight without changes to diet or exercise
- Feeling hungrier than usual but still losing weight
- Rapid weight loss over a stint
8. Fruity-Smelling Breath
A sweet, fruity odour on your breath can be more than just a sign you need to brush your teeth—it could indicate dangerously high blood sugar.
Why it happens: When your body can’t use glucose for energy, it burns fat instead, producing ketones. One type of ketone, acetone, can cause a fruity breath odour.
My experience: Fortunately, I never experienced this symptom, but it’s crucial to be aware of it as it can indicate a serious condition called diabetic ketoacidosis.
What to watch for:
- A sweet, fruity odour on your breath that doesn’t go away with teeth brushing
- This symptom is accompanied by nausea, vomiting, or abdominal pain
9. Nausea and vomiting
Feeling sick to your stomach, especially if it’s accompanied by other symptoms on this list, could be a sign of high blood sugar.
Why it happens: Very high blood sugar levels can lead to diabetic ketoacidosis, which can cause nausea and vomiting.
My experience: I occasionally felt nauseous when my blood sugar was particularly high, especially if I had eaten a very carb-heavy meal.
What to watch for:
- Persistent nausea, especially after eating
- Vomiting without other signs of stomach flu or food poisoning
- Nausea accompanied by excessive thirst and frequent urination
10. Mood Changes and Irritability
If you find yourself feeling unusually irritable or experiencing mood swings, it could be your body signalling high blood sugar.
Why it happens: Blood sugar fluctuations can affect your mood and mental state. High blood sugar can make you feel cranky and agitated.
My experience: I noticed I was snapping at my family more often and feeling frustrated easily. Once I got my blood sugar under control, my mood stabilized.
What to watch for:
- Increased irritability or agitation for an obvious cause
- Mood swings that seem out of character
- Feeling anxious more often than usual
Understanding Blood Sugar Levels
To fully grasp the significance of these high blood sugar warning signs, it’s crucial to understand what constitutes normal and high blood sugar levels.
Normal Blood Sugar Levels
- Fasting (before meals): Less than 100 mg/dL
- 2 hours after meals: Less than 140 mg/dL
Prediabetes
- Fasting: 100-125 mg/dL
- 2 hours after meals: 140-199 mg/dL
Diabetes
- Fasting: 126 mg/dL or higher
- 2 hours after meals: 200 mg/dL or higher
It’s important to note that these are general guidelines. Your healthcare provider may set different targets based on your health status and needs.
Causes of High Blood Sugar
Understanding what causes high blood sugar can help you prevent it. Common causes include:
- Consuming too many carbohydrates: Carbs break down into glucose, raising blood sugar levels.
- Insufficient insulin: because of type because of type 1 diabetes or advanced type 2 diabetes.
- Insulin resistance: When your body doesn’t use insulin effectively (common in type 2 diabetes).
- Stress: Stress hormones can cause blood sugar to rise.
- Illness or infection: Being sick can cause your body to release hormones that raise blood sugar.
- Certain medications: Some drugs, like steroids, can increase blood sugar.
- Dehydration: Not drinking enough water can concentrate glucose in the blood.
- Dawn phenomenon: A natural rise in blood sugar in the early morning hours.
Complications of Untreated High Blood Sugar
Ignoring high blood sugar warning signs can lead to serious health complications over time:
- Cardiovascular disease: Increased risk of heart attack, stroke, and blood vessel problems.
- Nerve damage (neuropathy): can cause tingling, numbness, and burning sensations, especially in feet and hands.
- Kidney damage (nephropathy): This may lead to kidney failure or irreversible end-stage kidney disease.
- Eye damage (retinopathy): Can cause vision problems and potential blindness.
- Foot damage: Reduced blood flow and nerve damage increase the risk of foot complications.
- Skin conditions: Increased susceptibility to skin infections and slow healing.
- Cognitive decline: Some research suggests a link between type 2 diabetes and increased risk of Alzheimer’s disease.
- Depression: People with diabetes have a higher risk of depression.
When to see a doctor
If you’re experiencing any of the high blood sugar warning signs mentioned above, especially if you have multiple symptoms, it’s crucial to consult a healthcare provider. Seek immediate medical attention if you experience:
- Severe abdominal pain
- Persistent vomiting
- Breath that smells fruity or like acetone
- Extreme fatigue
- Confusion or difficulty staying awake
These could be signs of diabetic ketoacidosis, a life-threatening condition that requires immediate treatment.
