UTIs such as Cystitis occurs when bacteria get into your urethra, causing an infection. Such an infection, according to Dr. Jennifer Robinson of WebMD, can causes:

  • A burning sensation when urinating
  • Fouls smelling urine
  • Pelvic pain

2. Anemia

Anemia is a common blood condition, especially in children and women. It is a condition characterized by a deficiency of red blood cells or hemoglobin in the blood.

A common symptom of anemia is cold feet and hands. With anemia, when small blood vessels in your extremities receive too little iron, they are more likely to drop in temperature. A continued drop in temperature may lead to chills without a fever.

Other symptoms of anemia will include:

  • Clinical depression
  • Fatigue and weakness
  • Skin color changes
  • Irregular heartbeat

Like other medical conditions, anemia can be prevented by cutting down on alcohol consumption, eating iron-rich foods, or taking iron supplements.

3. Sepsis or blood poisoning

Sepsis or blood poisoning, medically known as septicemia, is a life-threatening blood infection known to cause organ failure, clotting, and sudden drop in blood pressure. Chills without fever or with fever are common symptoms of this condition.

4. Hypothyroidism

Hypothyroidism or underactive thyroid occurs when your thyroid glands do not produce enough thyroid hormones. Thyroid hormones regulate how your body uses energy.

An underactive thyroid causes chills because your body uses less energy, thus generates less heat. When suffering from this condition, you will find it hard to handle cold temperatures.  Remembers chills help your body generate temperature.

Common symptoms of an underactive thyroid will include:

  • Anxiety and depression for no apparent reason
  • Fatigue and weakness
  • Pain in joints
  • Sudden weight gain
  • Abnormal menstrual periods in women

Hypoglycemia is the other possible cause of chills. It is a clinical syndrome that results from low blood sugar, especially in people with diabetes. Common symptoms of this condition will include the following:

  • Blurry or double vision
  • Anxiousness
  • Heart palpitations and erratic heartbeat
  • Sudden shaking and tremors
  • Intense hunger

If you are diabetic, then the medication and insulin may help control the level of blood sugar level. If however you develop hypoglycemia and you are not diabetic, then you can prevent this condition by doing the following:

  • Increase your consumption of carbohydrates
  • Cut down on alcohol consumption and tobacco use
  • You can schedule regular appointments with your health care provider to ensure you monitor your blood glucose

  • Mild to severe chest pains
  • Trembling
  • Pounding heart
  • Dizziness
  • Lightheadedness

Chills without fever during pregnancy


Chills with no fever can also occur during pregnancy. In such cases, it could be a sign of any of the following conditions:

8. Malnutrition

Malnutrition during pregnancy is a leading cause of disease and other infections. During pregnancy, a lack of vital nutrients makes you vulnerable to viral and bacterial infection. Your body may also lack the energy to perform basic functions.

Malnutrition can be as a result of:

  • Digestion and absorption issues
  • Secondary health issues
  • Insufficient foods

Malnourished individuals often lack proper heat. This can be attributed to the lack of stored body fat. It is thus possible to feel cold even with no fever. Malnutrition can thus cause chills, shivers, and lightly tingles in extreme cases.

One can prevent malnutrition by maintaining a proper healthy diet, limiting their intake of junk and processed food, and in extreme cases, vitamin and nutritional supplements may be used.

9. Hypothermia

Hypothermia is also a possible cause of chills without fever, not only during pregnancy but also when not. It happens when your body fails to adjust to the loss of heat in extreme environments. In such cases, you may start to lose sensation in the extremities. This can be followed by the weakening of muscles and diminished consciousness.

10. Insomnia

Lack of enough sleep or insomnia during pregnancy leaves your body prone to disease and infections. Normally, your body temperature drops when asleep, so not having enough sleep may cause this to happen when you are awake.

The chills, shiver, and uncontrolled shaking you experience due to insomnia may be your body’s way to keep you warm.

During pregnancy, you can prevent insomnia by:

  • Not taking stimulants such as coffee when going to bed

Long exposure to cold environments can be bad for your health, especially when pregnant.

Symptoms of chills without fever

Chills are normal and will often manifest from two situations.  The first one is the normal physiological reaction to cold, and the other is the one accompanying fever. With chills, the muscles of your body continue to contract and relax rapidly to raise your body temperatures.

There are some symptoms that will show you have chills but no fever. Common one includes the following:

  • Sweating, as your body continues to generate more heat, some body parts like your armpit will start secreting more sweats as a result. In a cold environment, your skin may feel sticky and clammy.
  • Shivering or uncontrolled shaking this is the result of the contraction and relaxation of your muscles to generate heat
  • Chattering teeth, this is also caused by muscles contraction
  • Some people may develop goosebumps

Night sweats and chills without fever

Night sweat or hyperhidrosis accompanying the chills without a fever is often associated with a variety of serious illnesses.  It is important to note that night sweats are different from primary hyperhidrosis. Unlike with the night sweat, primary hyperhidrosis is characterized by excessive sweating from one area of the body.

For night sweats, physicians are unable to discern the cause it the symptoms appear without an associated illness.  So what causes night sweats and chills but no fever?

The most likely causes of these symptoms will include the following conditions:

  • Hypoglycemia is a condition marked with a deficiency in blood glucose. This condition can be shown by symptoms such as anxiety, shaking or trembling, sweating, dizziness, and confusion among other temperatures.
  • Hyperthyroidism is a condition caused by the secretion of too much thyroid hormones that control metabolism. Increased metabolism may result in increased body heat, which causes night sweats, tremors, insomnia, anxiety, and heart palpitation, among other symptoms.
  • Viral and bacterial infections can cause chills, which are the body’s mechanism to increase temperature. night sweats in such cases can serve to regulate this temperature

Uncontrollable shaking and chills

Chills or uncontrolled shaking is a common symptom of hypothyroidism. Hypothyroidism is a condition marked by an abnormally low activity of the thyroid gland. This condition is also called underactive thyroid disease.

With an underactive thyroid, the thyroid gland located in the front of your neck fails to make enough thyroid hormone. These hormones travel through your bloodstream and affect nearly every part of the body. They control how your body cells use energy, a process known as metabolism. Your body affects your body temperature, heartbeat, and how well your body burns calories.

Other common causes of uncontrollable shaking and chills will include the following:

  • Long exposure to cold temperatures
  • Viral and bacterial infections
  • A drop in blood sugar level
  • Being under extreme anxiety or depression

In most cases, the uncontrollable shaking may serve to increase the core temperature. When the shivering is caused by cold, for instance, warming yourself up can help gradually stop the shaking. On the other hand, is the shaking and chills are caused by an underlying medical condition, then treating the said condition is the best way to stop the shaking.

Chills without fever and stomach pain

When chills without fever and stomach pain occur, it is likely to be a symptom of inflammation. The blood test (morphology, CRP) and urinalysis are usually sufficient for initial diagnosis.

The discovery of the source might become more challenging. However, based on the results of these standard analyzes and full medical history, the doctor should be able to establish a further diagnostic plan.
