Chills

Chills(發冷) or shivering are your body's way of raising your core body temperature through muscular contraction that is under hypothalamic regulation. It can be caused by conditions such as low environmental temperatures, infections, toxins or hormonal imbalance. When the core body temperature drops below 35 degrees, life-threatening hypothermia may ensue. You must seek medical advice as soon as possible to find out the cause of the chills and treat them.

Chills causes

Bacterial infections such as listeria, pneumonia, and urinary tract infections
Cancer such as leukemia
Hypothyroidism
Gastroenteritis
Anemia
Detoxification
Hangover
Low blood sugar
Menopause
Panic attack
Parasitic infections such as giardiasis
Septicemia
Influenza
Vaccination
Receive general anesthesia

Have an accident or experience a traumatic event

Characteristics of chills

Body trembling or shaking
Teeth chattering, jaw rattling, teeth sometimes knocking together
Chicken skin
Body pain

Investigational modalities for chills

To know the root cause of chills, your doctor will generally ask about the medical history of the present condition and perform a physical examination, adjuncts to investigation would include:

Blood collection and culture tests

Analyse for the presence of bacteria and other microorganisms that cause infectious diseases

Blood tests for complete blood picture and hormone levels

Look for elevations/abnormalities in white blood cell count, thyroid hormone levels

Collect and examine sputum

Testing for microorganisms that cause inflammation and infection

Urine chemistry and bacteriology tests

Test for bacterial infection

Antigen and PCR testing panels

Usually for rapid screening of possible presence of pathologic organism

Chest X-ray to rule out pneumonia

Tuberculosis and other infectious pulmonary diseases

CT scan, MRI

To investigate bone, soft tissue, brain and spinal cord inflammatory and/or infectious conditions

Home care and treatment for chills

Move to a warm place
Wear warm clothes and use blankets to keep warm
Drink hot drinks such as hot soup, hot tea, etc. to increase body temperature
Keep enough water
Adequate rest can help your body recover

Using antibiotics to treat bacterial and parasitic infections and antivirals to treat viral infections, as directed by a physician
Over-the-counter medicines such as acetaminophen (Paracetamol) or ibuprofen (Ibuprofen) to treat fever

How to prevent chills

Practice good hygiene: Frequent hand washing, especially after contact with other people in public places, can reduce the risk of infection and avoid contact with people with colds and flu.
Wear a mask: To prevent the spread of respiratory infections through aerosolized droplets via coughing or sneezing.
Strengthen the immune system: Eating a balanced diet, getting enough sleep, exercising regularly, and avoiding stress can all help strengthen the immune system, making the body better able to fight off infections.
Get Vaccinated: A flu vaccine, for example, can provide additional protection.
Keep warm: In cold weather, ensuring your body is warm can prevent hypothermia and avoid chills.
Stay in good physical condition: Manage chronic conditions such as diabetes, hyper- or hypothyroidism, renal failure and heart disease. These diseases may weaken the immune system and increase the risk of infection.
Get enough fluids: Maintaining a fluid balance helps your body function properly, including your immune response.

OT&P Medical Advice

Chills are part of the body’s thermoregulatory system to raise core temperature in response to such conditions as low environmental temperatures, infections, toxins or endocrine dysfunction. It can be self-limiting, however, life-threatening hypothermia (core body temperature below 35 degrees Celsius) can occur. Chills often also are a symptom of an ongoing infectious process, and you are advised to seek medical advice to address the cause as soon as possible. You are welcome to make an appointment with our doctors for consultation.
