Your Ultimate Guide To Understanding Normal Body Temperature: Causes, Symptoms, And Prevention

Body temperature is a vital sign that indicates the body's ability to produce and dissipate heat. A normal body temperature for a healthy adult is around 98.6°F (37°C), but it can vary slightly depending on factors such as time of day, activity level, and individual differences. In this guide, we will discuss the causes, symptoms, and prevention of abnormal body temperature.

Causes of abnormal body temperature:

Fever: The most common cause of abnormal body temperature is a fever, which is a sign of an infection or inflammation in the body. A fever is defined as a body temperature above 100.4°F (38°C).
Hypothermia: A low body temperature, known as hypothermia, can occur in cold environments or due to certain medical conditions. A body temperature below 95°F (35°C) is considered hypothermia.
Hyperthyroidism: An overactive thyroid gland can cause the body to produce too much heat, leading to a high body temperature.
Medications: Certain medications, such as antipsychotics and antidepressants, can affect body temperature regulation.
Trauma: Serious injury or surgery can cause the body to produce too much heat as a response to the trauma.

Symptoms of abnormal body temperature:

Fever: Symptoms of a fever can include sweating, chills, headache, muscle aches, and fatigue.
Hypothermia: Symptoms of hypothermia include shivering, numbness, confusion, and slow breathing.
Hyperthyroidism: Symptoms of hyperthyroidism include weight loss, rapid heartbeat, and sweating.

Prevention of abnormal body temperature:

Fever: The best way to prevent a fever is to practice good hygiene, such as washing your hands frequently, and avoiding close contact with people who are sick.
Hypothermia: To prevent hypothermia, it is important to dress warmly in cold weather, and avoid staying out in the cold for prolonged periods of time.
Hyperthyroidism: To prevent hyperthyroidism, it is important to manage any underlying medical conditions that can cause an overactive thyroid gland.
Medications: If you are taking medications that can affect body temperature regulation, it is important to follow your doctor's instructions and monitor your body temperature regularly.
Trauma: To prevent abnormal body temperature due to trauma, it is important to take steps to prevent injuries and accidents.

In conclusion, abnormal body temperature can be caused by fever, hypothermia, hyperthyroidism, medications, and trauma. It is important to be aware of the symptoms and take the necessary steps to prevent abnormal body temperature. If you have a fever or other symptoms of abnormal body temperature, it is important to seek medical attention.

When to Take Vitamin B12 Test – Signs to Look For

Vitamin B12 is one of the most essential vitamins for the body. It plays a major role in making red blood cells, maintaining nerve function, and supporting brain health. Unlike other vitamins, your body cannot produce Vitamin B12 on its own. It mainly comes from animal-based foods like meat, fish, eggs, and dairy.

In India, Vitamin B12 deficiency is very common, especially among vegetarians and vegans. Unfortunately, the symptoms are often ignored or mistaken for general tiredness or stress. This makes it important to recognize when to take a Vitamin B12 test so that treatment can start before complications arise.

Why is Vitamin B12 Important?

Vitamin B12 helps in:

Producing red blood cells
Preventing anemia
Supporting brain and memory functions
Keeping nerves healthy
Boosting energy levels

A deficiency can cause long-term health problems if not treated on time.

Key Signs You Need a Vitamin B12 Test

1. Constant Fatigue and Weakness

If you feel tired even after proper sleep, it could be due to low Vitamin B12. This happens because your body cannot produce enough healthy red blood cells, leading to less oxygen supply to tissues.

2. Numbness or Tingling Sensations

Vitamin B12 supports nerve health. Deficiency can cause nerve damage, leading to tingling or numbness in the hands and feet.

3. Memory Problems and Brain Fog

Difficulty in concentrating, forgetfulness, or confusion can be early signs of low Vitamin B12 levels.

4. Mood Swings and Depression

Low Vitamin B12 affects neurotransmitters that regulate mood. You may feel anxious, irritable, or even depressed.

5. Pale or Yellowish Skin

Since B12 deficiency causes anemia, your skin may appear pale or slightly yellow.

6. Unexplained Muscle Weakness

Weak muscles and difficulty walking can also be due to prolonged deficiency.

Who Should Get Tested?

Vegetarians and vegans (as B12 mainly comes from animal foods)
People above 50 years (absorption decreases with age)
Individuals with digestive disorders like Crohn’s or celiac disease
People who have undergone gastric surgery
Those taking long-term medications like metformin or antacids

How is the Vitamin B12 Test Done?

The Vitamin B12 test is a simple blood test. A small sample is taken from your vein and analyzed in the lab. No fasting is required unless your doctor suggests additional tests along with it.

Can Vitamin B12 Deficiency Be Treated?

Yes. Once diagnosed, treatment can be done in three ways:

Dietary changes – Eating more eggs, dairy, fish, or fortified cereals.
Supplements – Oral Vitamin B12 tablets or capsules.
Injections – For severe deficiency, doctors may recommend B12 injections.

Preventing Vitamin B12 Deficiency

Include B12-rich foods in your diet
If you’re vegetarian, choose fortified cereals and plant-based milk
Go for regular check-ups if you’re at risk
Discuss supplements with your doctor if needed

Conclusion

Vitamin B12 deficiency can easily be overlooked, but the symptoms often give early warnings. If you experience fatigue, numbness, mood changes, or memory issues, it may be time to book a Vitamin B12 test. Early detection ensures timely treatment and prevents long-term complications.

Don’t ignore your health—book your Vitamin B12 test today and take control of your well-being.
