What can you take to lower your blood sugar quickly

A person with diabetes can use various techniques to lower high blood sugar levels and reduce their risk of complications.

1. Monitor blood sugar levels closely

High blood sugar typically refers to levels over 180 mg/dl. However, a person often does not experience symptoms until the levels exceed 200 mg/dl. As such, it is essential for a person with diabetes to check their blood sugar several times a day. Doing so should mean that blood sugar levels never get excessively high.

A person with diabetes can use an at-home glucose monitor to check their blood sugar levels. One option is a continuous glucose monitor, which is a medical device that easily enables a person to check their blood sugar levels.

The recommended number of times to check glucose levels during the day will vary from person to person. A doctor can make the best recommendations regarding the frequency of testing.

2. Reduce carbohydrate intake

A low carb diet is one that limits the amount of carbohydrate a person consumes. Carbs raise blood glucose more than other foods, and evidence suggests that a low carb dietary pattern may help a person stabilize and manage their blood sugars.

However, this type of eating pattern may not be suitable for everyone. Therefore, before reducing their carbohydrate intake, a person may wish to consult a healthcare professional or a dietitian.

3. Eat the right carbohydrates

There are three main types of carbs:

• sugars
• starches
• fiber

Sugars and starches raise blood sugar levels, but fiber does not cause a blood sugar spike, as the body is unable to absorb and break down this type of carb. As such, people may consider including carbs that are richer in fiber in their diet.

People may also refer to sugars and starches as simple and complex carbs. Simple carbs primarily consist of one type of sugar. The body breaks these carbohydrates down very quickly, which causes blood sugar to rise rapidly. Complex carbohydrates consist of three or more sugars that are linked together. They result in a more gradual release of sugar into the body, meaning that blood sugar levels do not rise rapidly after a person eats them.

Some people may use the glycemic index (GI) to help them monitor how much sugar and carbohydrate they eat, which will, in turn, help them manage their blood sugar levels. The GI measures and ranks various foods by how much they cause blood sugar levels to rise.

Low GI foods describe those that score 55 or lower on the index. These foods include:

• sweet potatoes
• quinoa
• legumes
• low fat milk
• leafy greens
• nonstarchy vegetables
• nuts and seeds
• meat
• fish

4. Maintain a moderate weight

Reaching a moderate weight can help a person better manage their diabetes. The ideal weight range for a person varies among individuals, but a doctor can help provide guidance.

Evidence notes a link between obesity and type 2 diabetes. Research also highlights the relationship between obesity and insulin resistance. Insulin is the hormone that is responsible for allowing glucose in the blood to enter cells. Losing 5–10% of body weight can help those with excess weight improve their blood sugar levels.

5. Control portion size

At most meals, a person should follow portion guidelines. Eating a suitable portion size can make it easier to manage weight and control blood sugar levels. Many factors, such as weight, body composition, and activity levels, play a role in determining the ideal portion sizes. A doctor or dietitian can offer more specific advice on appropriate portion sizes for a person.

6. Exercise regularly

Exercise has many health benefits and can help a person manage their blood sugar levels. Notably, exercise can help by increasing insulin sensitivity, allowing muscle cells to use the hormone more effectively to take up glucose and use it for energy. This can help lower blood sugar in the short term. In the long term, regular exercise can help lower a person’s A1C test result.

7. Hydrate

Proper hydration is crucial for health, and it can help a person control their blood sugar levels. Dehydration is the term for the body having less water than it requires. It can cause blood sugar levels to spike, as less water in the body means that there is a higher concentration of sugar in the blood. Therefore, taking on more fluids can help lower blood sugar.

However, it is important to hydrate with water, as other beverages — such as fruit juices and sodas — can cause blood glucose to increase further.

8. Try herbal extracts

Some people may consider using herbal supplements to help control their blood sugar. Although some research suggests that they may have a positive effect, more evidence is necessary to support these claims. Additionally, some herbs can interact with other medications and result in side effects. As such, a person should discuss any supplements with a doctor before taking them.

Some supplements that may help include:

• certain teas
• ashwagandha
• ginseng
• fenugreek
• turmeric
• bitter melon
• cinnamon

9. Manage stress

Stress has a significant effect on blood sugar levels. The body releases stress hormones when it is under tension, such as when a person is ill or experiencing emotional stress, and these hormones can raise blood sugar levels.

Evidence notes that managing stress through exercise and allowing time for rest and relaxation can help lower blood sugar levels.

10. Get enough sleep

Getting adequate sleep can help with diabetes management. Evidence indicates that most adults should aim for 7 or more hours of sleep per night.

Insufficient sleep can have various effects on the body, including:

• increasing insulin resistance
• increasing hunger
• causing cravings for foods high in carbs and sugar
• making it more difficult to maintain a moderate weight
• raising blood pressure
• impairing the ability of the immune system to fight infection
• increasing the risk of depression and anxiety

Multiple factors, such as dietary patterns, health, and medications, can influence a person’s blood sugar levels. A person can seek a doctor’s advice on the best strategies to manage their blood glucose. As an individual’s blood sugars can fluctuate and go down quickly, it is important to monitor them closely.

Typically, medications such as insulin can help reduce blood sugars quickly. Different types of insulin exist, and each type has a different onset and duration — meaning how long it takes to work and how long the effects last, respectively.

For example, rapid-acting insulin typically begins to work within about 15 minutes, has the strongest effect in approximately an hour, and lasts for a few hours.

Other methods, such as exercise, can help lower blood sugars for up to about 24 hours by making the body more sensitive to insulin. Generally, it is advisable to exercise 1–3 hours after eating, as this is likely when blood sugar levels will be highest. However, it is important to check these levels before exercising and to check them regularly, particularly after any grueling activity.

If a person takes insulin, their risk of experiencing hypoglycemia may be highest 6–12 hours after exercising. Additionally, it is worth noting that health experts advise caution if exercising with high blood sugars, as physical activity may cause them to rise even higher.

Managing blood sugar levels to prevent hyperglycemia is vital to avoid serious complications from diabetes. A range of lifestyle interventions can help a person lower their blood sugar levels and keep them within the target range. A person can work with their diabetes healthcare team to plan strategies and targets.
