How to bring Blood Sugar down Fast if over 250

High blood sugar is a very common problem faced by numerous people suffering from diabetes. If left unchecked this problem can lead to serious complications. High blood sugar can lead to various problems such as nausea, dizziness, headache, even loss of consciousness. So it’s important to get your blood sugar down fast if it is high.

Your blood sugar might be high for various reasons, but one of the most common reasons in the world today is Diabetes mellitus.

High blood sugar or Hyperglycemia

Hyperglycemia is the condition of the body where the blood sugar level is more than 7 mmol/L or 125 mg/dL. In this case, the body faces a number of problems as the high sugar content in the blood hampers the internal balance of the body. It causes different metabolic and physiological complications which in turn, prevents the body from operating at its optimal condition.

Hyperglycemia is principally caused by Diabetes mellitus. However, it can also be caused by illnesses such as hormone disorders, infections, taking too much food, excessive weight, lack of physical exercise. And due to the side effects of some specific kinds of medication.

The symptoms of high blood sugar include:

  • Frequent thirst and dryness of mouth
  • Repeated urination
  • Blurry vision
  • Headache
  • Mental confusion
  • Delirium
  • Tiredness
  • General weakness
  • Nausea
  • Vomiting

If hyperglycemia is not controlled in time, it can cause many long term complications.

Some severe complications of hyperglycemia are:

  • Diabetic ketoacidosis
  • Coma
  • Acute circulatory failure
  • Hypokalemia
  • Infection
  • Coronary artery disease
  • Peripheral vascular disease
  • Kidney problems
  • Loss of vision
  • Paralysis
  • Diabetic cataract

High blood sugar and Diabetes:

Diabetes mellitus is a syndrome that is characterized by impaired carbohydrate, fat, and protein metabolism caused by either the lack of insulin secretion or decreased or ineffective function of insulin.

There are two types of diabetes; type 1 and type 2. Type 1 is caused by inadequate insulin production in the body whereas type 2 is caused by insulin resistance of the body tissue. Type 2 diabetes is often associated with obesity. It’s caused by the reduced sensitivity of insulin receptors which causes insulin resistance.

Most diabetics today are suffering from type 2 diabetes, where the body isn’t able to use the insulin produced to break down the glucose which is taken within the diet. This results in sugar remaining in the bloodstream and causing high blood sugar or hyperglycemia.

Type 2 diabetes is normally caused due to genetic predisposition for an excessive fatty diet with high sugar content. Diabetes mellitus is a permanent condition and it can’t be reversed. However, with medication, proper diet, and a disciplined lifestyle, diabetes can be controlled and the effects of high blood pressure can also be subsequently reduced.

The normal range of blood sugar:

In case of a normal individual, the blood sugar level after fasting for at least 8 to 12 hours is less than 6.1mmol/L or less than 110 mg/dL. 2 hours after intake of glucose, the blood sugar level should be less than 7.8 mmol/L or less than 140 mg/dL. If your blood sugar level is more than 7 mmol/L or more than 125 mg/dL after fasting and more than 11.1 mmol/L or 200 mg/dL 2 hours after glucose intake, then you might have Diabetes mellitus.

normal range of blood sugar

If you are experiencing any symptoms related to obesity like high blood sugar, tiredness, swelling of the body, problems in vision, nausea, dizziness, etc. or any of your family members or close relatives are diabetic, it’s wise to have yourself tested for diabetes or any insulin related complications.

What should I do if my blood sugar is over 250?

If your blood sugar is nearing 250 mg/dL, then it is near the critical level or danger zone and you are under the risk of severe hyperglycemic shock or diabetic coma. In such a case, you should see a doctor immediately.

The doctor may prescribe you insulin until your blood sugar level returns to normal along with oral medications.

You also need to change your dietary habits drastically and avoid sugar producing foods. Foods containing carbohydrates, glucose, and high amounts of sugar should be taken in restricted amounts. You should also exercise every day to reduce your blood sugar level.

What should I do if my blood sugar is over 300?

If your blood sugar level is over 300 mg/dL, then you are at extreme risk of diabetic ketoacidosis and hyperglycemic shock. Your body begins to suffer from the toxic effect of ketones produced in your body due to a lack of glucose available to the tissue as well as complications due to extremely high blood sugar.

In such a case contact emergency services and go to the hospital at once. You will be treated with insulin and other IV medications immediately and placed under observation due to the risk of falling into a coma.

If you suffer from chronically high blood sugar and uncontrolled diabetes, you should regularly check your ketone level by urine dipstick test. If you see that your urine contains heavy amounts of ketone, contact your doctor, and seek medical advice.

What should I do if my blood sugar is over 400?

If your blood sugar is over 400 mg/dL, then it is considered a medical emergency. In such a case you might lose consciousness or even collapse due to hyperglycemic shock.

If anyone is suffering from such a severe case, they should immediately be taken to the hospital for immediate medical attention. At this extreme level of hyperglycemia, patients fall into a diabetic coma. it is a serious condition that may cause permanent brain damage or even death if left untreated.

In such an emergency, normally insulin is administered immediately along with IV. Moreover, special care is taken to prevent the patient from going into circulatory shock and ultimately cardiac arrest.

If you are a diabetic make sure to check your blood sugar regularly and report to your doctor. If you see that your blood sugar is rising gradually over 200 mg/dL in the course of a few days, immediately contact your doctor and seek medical advice.

Medication to reduce High blood sugar:

In the case of uncontrolled blood sugar, usually, medication is the only way to reduce blood sugar down to normal levels.

Most people with type 2 diabetes can achieve their target blood sugar levels with proper diet and adequate exercise but medications are always necessary to reduce the risk of damage due to high amounts of blood sugar.

The decision about which medications are advised to depend on various factors including blood sugar level, age, sex, other health problems, etc.

If you are suffering from high blood sugar, do not attempt to take any of these medications without the guidance of your physician.

Common medications prescribed to reduce high blood sugar:

  • Metformin – It lowers glucose production in the liver and improves your body’s sensitivity to insulin so that your body uses insulin more effectively.
  • Sulfonylureas – Helps your body secrete more insulin.
  • Meglitinides – They stimulate the pancreas to secrete more insulin, they’re faster acting, and the duration of their effect in the body is shorter.
  • Thiazolidinediones – It makes the body’s tissues more sensitive to insulin.
  • DPP-4 inhibitors – It helps reduce blood sugar levels but has a very modest effect.
  • GLP-1 receptor agonists – They slow digestion and help lower blood sugar levels.
  • SGLT2 inhibitors – They prevent the kidneys from reabsorbing sugar into the blood.
  • Insulin – Some with type-2 diabetes need insulin therapy.

How insulin works to reduce blood sugar

Insulin is the principal hormone in the body responsible for blood sugar control. It is produced in the pancreas inside a cluster of cells called the Islets of Langerhans. These cells produce insulin and then release it directly into the bloodstream. Insulin production is stimulated after the body detects the presence of glucose and other carbohydrates in the food that is ingested. This triggers the pancreas to release Insulin. Insulin works by activating glucose transporters in the cell membranes and stimulates glucose uptake by muscle and fatty tissues.

Some of the important functions of Insulin are as follows:

  • Insulin promotes uptake utilization and storage of glucose by most tissues. Especially muscles, fatty tissue, and liver.
  • Insulin increases the production and storage of fats and inhibits the metabolism of fats.
  • It promotes the synthesis of new protein in the body, prevents protein degeneration, and helps increase in body growth.
  • Insulin stimulates the conversion of glucose into glycogen inside the muscles which is later used as fuel.
