How To Test For Ketones

Hypoglycemia – What Causes Low Blood Sugar Levels

You can use a urine test strip or blood ketone meter and ketone test strip to test for ketones at home. Testing either urine or blood is important, but when possible, a blood test is preferred because it gives you and your care team more precise information about your ketone levels. Because urine may have been in the bladder for some time, the results from these tests may show levels that are either higher or lower than the ketone levels that are actually circulating in your body. It is also very important to know that urine test trips degrade over time, so if you are using this method, you need to look at expiration dates carefully.

Your diabetes care team can give you specific directions about when you should check for ketones, but in general, you should check for them when your blood glucose is 240 mg/dL or higher. You should also check for ketones if you notice any of the DKA symptoms listed above or if you are sick it is possible to have ketones while your blood glucose levels are within range .

At-home urine test strips will change color to show the level of ketones in the urine. They typically report results as negative, trace, small, moderate or large. Blood ketone meters will provide a number that indicates the ketone levels. The following ranges are generally used:

Why Do I Feel Chills But No Fever

A fever is an abnormally high body temperature. A normal body temperature usually ranges from 36.5oC to 37.2oC, or 97.8oF to 99oF. A person with a fever experiences a temperature spike, often starting from 37.2oC or 99oF.


While a fever is technically not an illness, it is often a symptom of one, usually an infection. In order to counteract the infection, the hypothalamus in the brain sends signals to raise the bodys temperature.1 When the rest of the body detects this heat increase, it starts working overtime to regulate its new, higher temp. This often leads to chills which can be experienced as sudden, uncontrollable tremors all over the body.

Though usually chills are accompanied by a fever, that’s not always the case. There are medical conditions which may manifest as chills without a fever. These may include the following, which are all described in detail below.

  • Cystitis or infection of the bladder
  • Complications with prescription medicine

Frostbite, hypothermia, shivering, hunger, nausea, fatigue

Wear warm clothing, avoid excessively cold environments

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 they’re doing, or by a trained healthcare professional.

You should dial 999 to request an ambulance if:

  • a glucagon injection kit isn’t available
  • there’s nobody available who’s trained to give the injection
  • the injection is ineffective after 10 minutes

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

If you’re 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.

Side Effects Of Medication

Some chills are the result of the bodys response to taking medications and adjusting or stopping medications:

  • Diabetes medications: Insulin and drugs like sulfonylureas and meglitinides that increase insulin secretion by the pancreas can cause hypoglycemia-related chills. This happens if you have too much insulin and havent matched it with your food intake or physical activity level.
  • General anesthesia for surgery: People can experience chills upon waking from anesthesia.
  • Chemotherapy medications: Medications that you are taking to calm down your immune system and chemotherapy to fight cancer can have flu-like side effects, including fever and chills. Symptoms typically peak and resolve after treatment over a few days.

Make note of medication side effects to discuss with your healthcare provider. In severe cases, a healthcare provider may be able to prescribe other drugs to help you cope with your chills when they result as side effects to medications you are on.

Exercise Food And Alcohol

Lowering Blood Sugar: can low blood sugar cause kidney damage

For people with type 1 diabetes, maintaining the correct blood glucose level involves balancing how much insulin you inject, the amount of food you eat, and how much energy you burn during exercise.

Hypoglycaemia may occur if you’ve taken your dose of insulin as usual, but your carbohydrate intake is lower than normal or has been used up more quickly. This may happen if you delay or miss a meal or snack, don’t eat enough carbohydrate, or exercise more than usual.


People with diabetes who’ve drunk too much alcohol, or drank alcohol on an empty stomach, can also get hypoglycaemia.

However, it’s not always possible to identify why a particular episode of hypoglycaemia has occurred, and sometimes it happens for no obvious reason.

What Causes Low Blood Glucose In People With Diabetes

Low blood glucose levels can be a side effect of insulin or some other medicines that help your pancreas release insulin into your blood. Taking these can lower your blood glucose level.

Two types of diabetes pills can cause low blood glucose


  • sulfonylureas, usually taken once or twice per day, which increase insulin over several hours
  • meglitinides, taken before meals to promote a short-term increase in insulin

The following may also lower your blood glucose level

The Effects Of Low Blood Sugar On Your Body

Every cell in your body needs energy to function. The main source of energy might come as a surprise: Its sugar, also known as glucose. Blood sugar is essential to proper brain, heart, and digestive function. It even helps keep your skin and vision healthy.

When your blood sugar levels fall below the normal range, its called hypoglycemia. There are many identifiable symptoms of low blood sugar, but the only way to know if you have low blood sugar is by taking a blood glucose test.

Learn more about the symptoms of low blood sugar, as well as the long-term effects on the body.

most common reasons for low blood sugar are some medications used to treat diabetes, such as insulin.


In type 1 diabetes, the pancreas can no longer produce insulin. In type 2 diabetes, the pancreas doesnt make enough insulin, or your body cant use it properly. Too much insulin or oral diabetic medication can lower the blood sugar level, leading to hypoglycemia.

However, contrary to popular belief, low blood sugar isnt exclusive to diabetes, though it is rare. It can also happen if your body makes more insulin than it should.

Another possible cause of low blood sugar is drinking too much alcohol, especially over long periods of time. This can interfere with the livers ability to create a buildup of glucose and then release it into your bloodstream when you need it.

Other causes include:

How Long Will The Effects Last

The effects of low blood sugar will continue and may even get worse until treatment brings your blood sugar level back to normal. It may take several minutes for the symptoms to go away after you start treatment. This may be a temporary problem while you and your healthcare provider are adjusting your medicine. If you are always prone to having low blood sugar, you may need to take special care for the rest of your life to keep your blood sugar at the proper level.

Hyperosmolar Hyperglycemic Nonketotic Syndrome : When Hyperglycemia Becomes Severe For People With Type 2 Diabetes

Hypoglycemia (Low Blood Sugar): Causes And Symptoms

Hyperosmolar hyperglycemic nonketotic syndrome is very rare, but you should be aware of it and know how to handle it if it occurs. HHNS is when your blood glucose level goes way too highyou become extremely hyperglycemic. HHNS affects people with type 2 diabetes.

HHNS is most likely to occur when you’re sick, and elderly people are most likely to develop it. It starts when your blood glucose level starts to climb: when that happens, your body will try to get rid of all the excess glucose through frequent urination. That dehydrates your body, and you’ll become very thirsty.

Unfortunately, when you’re sick, it’s sometimes more difficult to rehydrate your body, as you know you should. For example, it might be difficult to keep fluids down. When you don’t rehydrate your body, the blood glucose level continues to climb, and it can eventually go so high that it could send you into a coma.

To avoid hyperosmolar hyperglycemic nonketotic syndrome, you should keep close watch on your blood glucose level when you’re sick .


Talk to your healthcare professional about having a sick-day plan to follow that will help you avoid HHNS.

You should also be able to quickly recognize the signs and symptoms of HHNS, which include:

  • Extremely high blood glucose level

  • Dry mouth

How Can I Prevent Hypoglycemic Episodes

The key to preventing hypoglycemic events is managing diabetes:

  • Follow your healthcare providers instructions about food and exercise.
  • Track your blood sugar regularly, including before and after meals, before and after exercise and before bed.
  • Take all your medications exactly as prescribed.
  • When you do have a hypoglycemic event, write it down. Include details such as the time, what you ate recently, whether you exercised, the symptoms and your glucose level.

Can A Simple Fever Be That Bad For A Diabetes Patient

No doubt youve heard the advice, Drink plenty of fluids, for a fever. This is because fever causes considerable fluid loss through the skin as perspiration. Your loss of fluid can be difficult to estimate, so your physician may want to assume that youd require 12 more quarts of fluid daily than youd normally need. Ordinarily, a mild fever helps to destroy the infectious agent that caused the fever. The tendency to sleep out fever may also be beneficial.


For a diabetic, however, the somnolence that you experience with fever may discourage you from checking your blood sugar, covering with insulin, drinking adequate fluid, and calling your physician every few hours. If you dont have someone awaken you every 20 minutes, you should use aspirin, acetaminophen , or ibuprofen , in accordance with your doctors instructions, to help fight the fever. Beware, however, that aspirin can cause false positive readings on tests for urinary ketones, so dont even test for ketones if you are using aspirin. Never use aspirin or ibuprofen for fever in children because of the risk of Reyes syndrome. Excessive doses of aspirin or NSAIDs can cause severe hypoglycemia. If at all possible, try not to use NSAIDs, as the combination of these drugs with dehydration can cause kidney failure. Acetaminophen can be highly toxic if used in doses greater than those indicated on the package label.

Staying Safe In Cold Weather

While it is ideal to just stay indoors and bundle up when the weather is chilly, real life often requires you to leave the house even in cold weather. Here are some tips to help you keep warm:

  • Wear multiple layers of clothes to stay warm outdoors. Protect your hands and feet with thick gloves and socks, and a pair of waterproof, insulated shoes. Consider wearing a cap, bonnet, or hoodie, especially if the weather is damp. Ear muffs are also helpful, especially when it is snowing.
  • Take plenty of water to keep yourself hydrated. This will help boost your immune system and make you more resilient against flu and cold viruses. Vitamin C supplements are also helpful to strengthen your immune system.
  • When you experience frostbite, do not rub or massage the affected area. Instead, use a hot compress or heating pad to raise its temperature. Stay near a source of heat, like a fireplace or radiator, or even a cooking stove, to lessen the effects of frostbite and return your body temperature to normal.

How Is Hypoglycemia Treated

When blood sugar levels are low, the goal is to get them back up into the healthy range quickly. Here are the basic steps to follow if your child is alert and awake:

  • Check blood sugar levels if you can to find out if symptoms are from hypoglycemia. If you can’t, don’t delay treating your child’s symptoms. You can always test after treating your child.
  • Give sugar. Offer your child a sugary food or drink that will raise their blood sugar quickly. Regular soda, orange juice, or cake frosting are good choices. Or, give your child a glucose tablet or gel. Follow your childs care plan for the right amount of sugar to give your child. Symptoms usually stop about 10 minutes after your child takes sugar.
  • Check blood sugar level again 15 minutes after giving sugar to make sure the level is no longer low.
  • Give food to help prevent the blood sugar from dropping again. Good choices are crackers with cheese, crackers and peanut butter, or half a turkey sandwich.

If theres no improvement or symptoms get worse, give glucagon right away. Then call 911. After getting glucagon, your child will be more alert and feel better within 15 minutes. When your child is alert enough to eat, give sugary food or drink to help prevent their blood sugar from falling again.


If you give your child glucagon, tell the doctor who manages your childs diabetes that you gave it. An episode of severe low blood sugar could be a sign that the diabetes care plan needs to be changed.

Hypoglycemia In Children: Pediatric Ketotic Hypoglycemia

Some children experience pediatric ketotic hypoglycemia, a condition involving low blood sugar levels and high levels of ketones. If people do not have enough glucose to use as energy, the body begins to break down fat in the body instead. The body produces chemicals called ketones as a by-product of breaking down fat.

According to a 2019 study , pediatric ketotic hypoglycemia usually occurs due to poor intake of food, a gastrointestinal illness and vomiting, or a period of prolonged fasting. Severe metabolic and hormonal conditions may also cause pediatric ketotic hypoglycemia.

Pediatric ketotic hypoglycemia may affect children from 6 months old and often resolves after the age of 6 years.

Low Blood Sugar Levels

Uncontrollable shivering can be caused by low blood sugar levels. Shivering, in this case, is accompanied by a headache, dizziness, sweating, and rapid heartbeat. When people with diabetes take their insulin shot and forget to eat food or eat less food, they may end up having excessive insulin in their blood, which can lead to hypoglycemia or low blood sugar.

Other reasons for hypoglycemia are:

  • Alcohol abuse
  • Low carbohydrate intake
  • Skipping meals

When people with diabetes have low blood sugar levels, it can cause their body to uncontrollably shiver or shake. However, people without diabetes may also experience low blood sugar levels and uncontrollable shaking due to excessive alcohol intake, taking certain herbal supplements, and too much exercise.

It is recommended to eat small frequent meals throughout the day to help prevent a drop in the blood sugar level and prevent episodes of uncontrollable shaking from happening.

Low Blood Glucose During Sleep

Your blood glucose level can drop while you sleep and stay low for several hours, causing serious problems.7 Symptoms of low blood glucose while you sleep can include

  • crying out or having nightmares
  • sweating enough to make your pajamas or sheets damp
  • feeling tired, irritable, or confused after waking up

Although you may not wake up or notice any symptoms, low blood glucose can interfere with your sleep, which may affect your quality of life, mood, and ability to work. Having low blood glucose during sleep can also make you less likely to notice and respond to symptoms of low blood glucose during the day.
