What Causes Blood Sugar To Go Low

Treating An Episode Of Hypoglycaemia

The immediate treatment for hypoglycaemia is to have some sugary food or drink to end the attack.

For example, this could be:

• a glass of fruit juice or non-diet soft drink
• between three and five dextrose tablets
• a handful of sweets

At first you should avoid fatty foods and drinks, such as chocolate and milk, because they don’t usually contain as much sugar and the sugar they do contain may be absorbed more slowly.

After having something sugary, you should have a longer-acting carbohydrate food, such as a few biscuits, a cereal bar, a piece of fruit or a sandwich.

It will usually take around 15 minutes to recover from a mild episode of hypoglycaemia. If you have a blood glucose meter, measure your blood sugar again after 15 to 20 minutes. If it’s still too low , you should have some more sugary food or a drink before testing your levels again in another 15 to 20 minutes.

When treating someone else with hypoglycaemia, if the above treatment isn’t effective, you may be able to help them by applying glucose gel to the inside of their cheeks, and gently massaging the outside of their cheeks.

It may take 10 to 15 minutes before they feel better. This shouldn’t be done if the person is drowsy or unconscious because of the risk of choking.

Rebound Hypoglycemia After Eating

If sugar comes from the food you eat, why would blood sugar be low after eating? It may be due to a phenomenon called reactive hypoglycemia. This refers to low levels of blood glucose that react to high levels. According to Mayo Clinic, it can occur within 4 hours of eating a meal.

Say breakfast includes pancakes, syrup, and fruit juice. The meal is full of carbs: starch in the pancakes, added sugar in the syrup, and natural sugar in the fruit juice. Those carbohydrates get absorbed fast.

Blood sugar can skyrocket, especially in people who have prediabetes or diabetes. You may feel a sugar high, or burst of energy, within minutes to an hour of eating. Thenthe crash. The higher they fly, the harder they fall, is spot-on for blood sugar. If it went up, up, up, it will go down, down down, possibly below normal levels and into the range of hypoglycemia.

Causes Of Low Blood Sugar

There are many reasons why you may have low blood sugar, including:

• Taking too much insulin.
• Not eating enough carbs for how much insulin you take.
• Timing of when you take your insulin.
• The amount and timing of physical activity.
• Drinking alcohol.
• How much fat, protein, and fiber are in your meal.
• Hot and humid weather.
• Unexpected changes in your schedule.
• Spending time at a high altitude.
• Going through puberty.
• Menstruation.

If A Person Is Unconscious

If a person loses consciousness because of severe hypoglycaemia, they need to be put into the recovery position and given an injection of the hormone glucagon . The injection will raise their blood glucose level.

The injection should be carried out by a friend or family member who knows what theyre doing, or by a trained healthcare professional.

You should dial 999 to request an ambulance if:

• a glucagon injection kit isnt available
• theres nobody available whos trained to give the injection
• the injection is ineffective after 10 minutes

Never try to put food or drink into the mouth of someone whos unconscious as they could choke.

If youre able to give a glucagon injection and the person regains consciousness, they should eat some longer-acting carbohydrate food, such as a few biscuits, a cereal bar or a sandwich.

You should continue to monitor the person for signs of recurring symptoms in case they need to be treated again.

A Low Blood Sugar Level And Driving

You may still be allowed to drive if you have diabetes or you’re at risk of a low blood sugar level for another reason, but you’ll need to do things to reduce the chance of this happening while you’re driving.

You also need to tell the Driver and Vehicle Licensing Agency and your car insurance company about your condition.

Get medical help right away for a person with low blood sugar if the person is not alert or cannot be woken up.

What Causes Blood Sugar Fluctuations

Here is Why your blood sugar might be up and down or fluctuate too much:

• Taking the excessive or inadequate amount of diabetes medication
• Changes in diet patterns or food content such as eating fried food or high carbohydrate content
• Change in the activity level such as starting a new activity or exercise
• Stress and anxiety
• Variability in diabetes medication absorption, For example, insulin absorption can vary by up to 20% every injection
• Variability in carbohydrate consumption and incorrect nutritional labels

How To Calculate Your Blood Sugar Level: The Complete Guide

To get an accurate reading of your blood sugar level, the best and most effective method is using a glucose meter. This will involve a small prick in your finger so receive a blood sample. The strip is then inserted into the meter and tested.

You may be wondering what your reading should be. There is no normal reading, an ideal reading differs from person to person. Everyone will get different readings at different times of the day. However, there is a rough range to determining a low, normal and high blood sugar level. Blood sugar level is read in mmol/L, which stands for millimoles per liter. Here is a guide as to what an ideal reading is for each diabetic type and non-diabetic patients:

It is advised to check it regularly if you are concerned, show regular symptoms or have diabetes. You should check before meals, exercise, before bedtime and after driving. Everyone is different so it is best to ask your doctor if you are unsure how many times and when you should check your blood sugar levels.

Research shows that over 50% who try to estimate their blood sugar level reading are incorrect. This may be due to over underlying medical conditions that did not know they had or poor lack of judgement. Therefore, this suggests it is very important to test at home to check in on your levels regularly to avoid any unnecessary future complications.

How To Prevent Low Blood Sugar

Small changes to your diet and physical activity habits can help prevent blood sugar spikes and decreases.

• Take smaller portions of high-carb foods, such as bread, pasta, potatoes, desserts, soft drinks and other sugar-sweetened beverages, and rice.
• Include a source of protein, fat, and/or dietary fiber when you eat carbohydrates.
• Choose less-processed versions of foods, such as whole fruit instead of juice, whole grains instead of refined, and pasta al dente instead of very well-cooked pasta.
• Instead of exercising on an empty stomach, have a small snack an hour or two before you start, or a larger snack or small meal three hours before.
• Have a snack or your next scheduled meal as soon as possible after exercising.

These changes can help prevent blood sugar swings.

When You Have Low Blood Sugar

First, eat or drink 15 grams of a fast-acting carbohydrate, such as:

• Three to four glucose tablets
• One tube of glucose gel
• Four to six pieces of hard candy
• 1/2 cup fruit juice
• 1 cup skim milk
• 1/2 cup soft drink
• 1 tablespoon honey

Fifteen minutes after you’ve eaten a food with sugar in it, check your blood sugar again. If your blood sugar is still less than 70 mg/dL, eat another serving of one of the foods listed above. Repeat these steps until your sugar becomes normal.

• Check your blood sugar level regularly and be aware of the symptoms of a low blood sugar level so you can treat it quickly.
• Always carry a sugary snack or drink with you, such as glucose tablets, a carton of fruit juice or some sweets. If you have a glucagon injection kit, always keep it with you.
• Do not skip meals.
• Be careful when drinking alcohol. Do not drink large amounts, check your blood sugar level regularly, and eat a carbohydrate snack afterwards.
• Be careful when exercising eating a carbohydrate snack before exercise can help to reduce the risk of a hypo. If you take some types of diabetes medicine, your doctor may recommend you take a lower dose before or after doing intense exercise.
• Have a carbohydrate snack, such as toast, if your blood sugar level drops too low while you’re asleep

The Dangers Of Low Blood Glucose

At some time, most people with diabetes experience the sweating and shakiness that occurs when blood glucose levels fall below 70 mg/dl a condition known as hypoglycemia. The average person with type 1 diabetes may experience symptoms of low blood glucose up to two times a week. However, not all are aware that these symptoms can rapidly progress to seizures, coma and even death if hypoglycemia is severe. Though hypoglycemia can be common and occur repeatedly in some people with diabetes, symptoms of low blood glucose should always be taken seriously. People with diabetes and their families, friends or coworkers should be prepared to act quickly and responsibly at the earliest signs of low blood glucose.

Treating Low Blood Sugar

If blood sugar is below 70 mg/dL, it should be treated by consuming food or drink containing 15 grams of carbohydrates.

Fruit juice and candies are preferred as they are rapidly absorbed into the bloodstream. It doesnt take much juice to get to 15 grams of carbohydrates about one-half cup will suffice.

Glucose tablets or glucose gels are a popular treatment for low blood sugar because theyre easy to have on hand in all different types of situations.

They dissolve quickly and provide pure glucose, so the blood sugar rapidly absorbs them to raise blood sugar. They are available over the counter without a prescription, so this is a convenient option for most people.

For cases of severe hypoglycemia, you can use a glucagon injection. Like insulin, glucagon is a hormone the pancreas produces. However, glucagon has the opposite effect as insulin as it stimulates the breakdown of liver glycogen stores into glucose, which raises blood sugar.

Medical professionals must prescribe glucagon injections. Theyre especially helpful to use when hypoglycemia is severe, or the person is too unresponsive to take in food or drink to treat the low blood sugar.

* An unresponsive person should always receive emergency medical treatment.*
