When an individual suffers from type 1 or type 2 diabetes, risky spikes in blood glucose (severe hyperglycemia) may mean he or she is required to lower blood sugar levels instantly. If they don’t, it may potentially cause life-threatening complications. A few main hyperglycemia symptoms include frequent urination, extreme thirst, and nausea.

Normal blood sugar levels are less than 100 milligrams per deciliter (mg/dL) after not eating (fasting) for at least 8 hours. And they’re less than 140 mg/dL 2 hours after eating.

What level of blood sugar is dangerous?

Broadly speaking, a blood glucose level of 180 milligrams per deciliter (mg/dL) is very high, however any blood glucose level (BGL) above your target range is cause of concern. Your doctor should tell you what is the upper limit is, as it vary for people to people.

There are many ways and norms that may help you in improving your blood sugar levels. They may also help lower the chance of complications associated with diabetes, such as:

1. Taking prescribed medication or insulin

Taking your prescribed insulin or oral diabetes medicine as directed by your doctor is essential for keeping blood levels healthy. Follow their suggestions for dose changes if needed. Always consult them if you face any problems or side effects from your drugs.

Insulin timing and dosages

Your doctor will decide the correct insulin dosage and timing based on your blood sugar levels, individual levels and lifestyle. Ensure that you follow their guidance consciously and adjust your dosage as required under their supervision.

Diabetes medications

Oral diabetes drugs like sulfonylureas, metformin, and DPP-4 inhibitors could also be prescribed by your doctor. These drugs work by increasing insulin sensitivity, aiding glucose absorption and boosting insulin production. Every time you take these drugs, as guided by your doctor.

2. Involvement in physical activity

Regular exercise is instrumental in managing health blood sugar levels. It enables your body to use insulin more effectively and amplifies glucose breakdown.

Aerobic exercises

Aerobic exercises such as stair climbing, walking, running, cycling, or swimming can cut down sugar levels. They do this by increasing insulin sensitivity and glucose metabolism. As suggested by the American Diabetes Association, involve 150 minutes of medium-intensity aerobic activity each week.

Resistance training 

Resistance training, such as weight lifting, can manage blood sugar levels by building muscle mass and elevating your body’s insulin sensitivity. Aim for two resistance training sessions per week on separate days.

Effect of different exercise intensities

Your workout intensity can mould your blood sugar levels. Higher intesity athletics may require more particular blood sugar control and tracking, on the other hand medium intensity workout are normally safe and helpful for all diabetes patients. Always consult your doctor before starting a new exercise.

3. Altering food intake

Conscious eating can significantly impact your blood sugar levels. Consider including healthier choices in your meals, like whole grains, vegetables, fruits and lean proteins. 

Low glycemic index foods

Consuming low glycemic index foods can assist in regulating your blood sugar levels. They result in a steady and slow glucose release into your bloodstream. 

The following are examples of foods with low glycemic index:

  • Legumes
  • Whole grains
  • Certain fruits 
  • Vegetables
  • Nuts

Fibre-filled foods 

Fibre-rich foods like fruits, whole grains and veggies can balance blood sugar levels. They perform this by slowing digestion and glucose absorption. 

Correct portion sizes

Proper portion sizes also assist in managing your blood sugar levels. Too much consumption can increase blood sugar, however not eating enough can drop blood sugar or cause hypoglycemia.

4. Remaining properly hydrated

Proper hydration is essential for keeping blood sugar levels healthy. Drinking water throughout the day can assist your kidneys in flushing out excess sugar via urine. It also avoids dehydration, which can negatively impact blood sugar control.

Water intake recommendations

The National Academies of Sciences, Engineering, and Medicine recommends a daily water intake of roughly 2.7 litres for women and 3.7 litres for men. Nevertheless, individual hydration requirements can differ based on multiple factors such as age, activity level, weight and climate.

5. Avoiding sugary beverages

Sweet drinks like juice, soda and sports drinks can create rapid surges in blood sugar levels and result in weight gain. Instead, choose water, herbal tea, or other zero-calorie beverages.

Monitoring blood sugar levels 

Regularly monitoring your blood sugar levels is a significant component of diabetes management. It enables you to make changes to your exercise, diet, and medication regimen to manage your blood sugar levels.

Regular blood sugar testing

Check your blood sugar levels consistently, as advised by your doctor. This may include testing before and after meals, before and after exercising, and during bedtime.

If you find that your blood sugar levels are too high or too low, consult your doctor for guidance on altering your diabetes management plan.

Making required adjustments

Depending on your blood sugar date, your doctor may recommend changes to your diet, medication regimen and exercise routine. This may assist you in managing your blood sugar levels.
