Top 10 Temperature Instability Causes

  1. 1.Viral (Norovirus) Infection

    Noroviruses are a group of related viruses that leads to nausea, vomiting, diarrhea, and cramps. These viruses cause gastroenteritis, an inflammation of the stomach and intestines. When the diarrhea and/or vomiting is severe, dehydration can occur. Symptoms of dehydration include a dry mouth, dizziness, urinating less frequently and dark urine.

    You can safely treat this condition at home. Make sure you drink plenty of water and fluids (Gatorade, Pediatlyte) to replace what is lost with diarrhea. If symptoms of dehydration occur or you are unable to keep down any liquids, seek care at your primary care physician or an urgent care.

    Rarity:
    Common
    Top Symptoms:
    fatigue, abdominal pain (stomach ache), nausea, headache, stomach bloating
    Symptoms that always occur with viral (norovirus) infection:
    hidden: gastroenteritis symptoms
    Symptoms that never occur with viral (norovirus) infection:
    severe abdominal pain, throbbing headache, severe headache, tarry stool
    Urgency:
    Self-treatment
  2. 2.Viral (Rotavirus) Infection

    Rotavirus is a virus that causes an infection of the gut, known as gastroenteritis. Symptoms include diarrhea, vomiting and fever. When the diarrhea and/or vomiting is severe, dehydration can occur. Symptoms of dehydration include a dry mouth, dizziness, urinating less frequently and dark urine.

    You can safely treat this condition at home. Make sure you drink plenty of water and fluids to replace what is lost with diarrhea. Eat as normally as possible. If symptoms of dehydration occur, or you are unable to keep down any liquids, seek care at your primary care physician or an urgent care.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, nausea, abdominal pain (stomach ache), headache, loss of appetite
    Symptoms that always occur with viral (rotavirus) infection:
    hidden: gastroenteritis symptoms
    Symptoms that never occur with viral (rotavirus) infection:
    constipation, tarry stool
    Urgency:
    Self-treatment
  3. 3.Influenza

    Influenza, or Flu, is an infection of the airway caused by the flu virus, which passes through the air and enters the body through the nose or mouth. The symptoms are similar to those of a cold, but the flu is usually more serious.

    If your flu-like symptoms are existing for less than 48 hours, it might be helpful to seek care by telephone or in a walk-in-clinic to get a course of oseltamivir (Tamiflu). Most people will get better on their own by drinking lots of fluids and taking an over-the-counter medication such as acetominophen (Tylenol) to help with aches or fever.

    Rarity:
    Common
    Top Symptoms:
    fatigue, headache, loss of appetite, cough, muscle aches
    Symptoms that never occur with influenza:
    headache resulting from a head injury
    Urgency:
    Phone call or in-person visit
  4. 4.Common Cold

    The common cold is a viral infection of the upper respiratory tract.

    The common cold is treated symptomatically. Since this is a viral infection, antibiotics are not effective. You can safely treat the symptoms of this condition with over-the-counter pain relievers, decongestants, antihistamines & cough medicines.

    Rarity:
    Common
    Top Symptoms:
    fatigue, headache, cough, sore throat, congestion
    Symptoms that never occur with common cold:
    being severely ill, severe muscle aches, rash, severe headache
    Urgency:
    Self-treatment
  5. 5.Viral Pneumonia

    Viral pneumonia is inflammation (irritation and swelling) of the lungs due to infection with a virus. Community-acquired pneumonia is the most common type, which is usually acquired in public areas such as at work, school, or grocery store.

    You should see a care provider to be treated and for evaluation of severity of your symptoms. Viral pneumonia is NOT treated with antibiotics, and you may find over-the-counter medications for pain and fever to be helpful.

    Rarity:
    Uncommon
    Top Symptoms:
    fatigue, headache, cough, shortness of breath, loss of appetite
    Symptoms that never occur with viral pneumonia:
    unexplained bruising
    Urgency:
    Primary care doctor

  6. 6.Bacterial Pneumonia

    Bacterial pneumonia is the infection of the lungs with bacteria (as opposed to a fungus or a virus).

    You should go see a doctor within the next day since this diagnosis requires a chest X-ray in addition to a doctor's assessment. Treatment with antibiotics is important to keeping the infection under control, which can become dangerous if it spreads or worsens within the lungs.

    Rarity:
    Common
    Top Symptoms:
    fatigue, cough, headache, loss of appetite, shortness of breath
    Symptoms that always occur with bacterial pneumonia:
    cough
    Urgency:
    In-person visit
  7. 7.Acute Viral Sinusitis

    Sinusitis is an inflammation of the sinus spaces behind the nose and cheeks. These spaces produce mucus, which drains into the nose. If the nose is swollen or if the mucus does not drain, this can block the sinuses and cause pain or infection.

    You can treat your symptoms at home using ibuprofen (for pain) and Tylenol (for a fever). Antibiotics for this diagnosis are not helpful because this is likely a viral infection.

    Rarity:
    Common
    Top Symptoms:
    headache, cough, sore throat, sinusitis symptoms, muscle aches
    Symptoms that always occur with acute viral sinusitis:
    sinusitis symptoms
    Symptoms that never occur with acute viral sinusitis:
    being severely ill
    Urgency:
    Self-treatment
  8. 8.Mononucleosis Infection

    EBV Mononucleosis is a clinical syndrome characterized by fever, sore throat, and swollen lymph nodes.

    You should visit your primary care physician within the next 24 hours. Diagnosis is confirmed by looking for antibodies against EBV. Treatment involves supportive care (hydration, antipyretics, and analgesics, such as acetaminophen and ibuprofen). Aspirin should not be given to children because of the possibility of Reye syndrome. It is also recommended that you do not do any strenuous physical activity and contact sports in the initial 3 to 4 weeks of illness due to the potential for splenic rupture.

    Rarity:
    Common
    Top Symptoms:
    fatigue, headache, loss of appetite, abdominal pain (stomach ache), cough
    Symptoms that never occur with mononucleosis infection:
    rectal bleeding
    Urgency:
    Primary care doctor
  9. 9.Acute Bacterial Sinusitis

    Acute bacterial sinusitis occurs when the sinuses become infected and, in turn, inflamed, which causes pain and other symptoms. The sinuses are air-filled cavities in the face that are generally clean and empty but when sick collect excess mucus and can become infected.

    You should visit a physician or urgent care facility in the next day or two. It’s likely your sinus infection is caused by a bacterial infection, which requires treatment with antibiotics. In the mean time, ibuprofen or acetaminophen can be taken to help with pain & fever.

    Rarity:
    Common
    Top Symptoms:
    fatigue, headache, cough, muscle aches, sore throat
    Symptoms that always occur with acute bacterial sinusitis:
    sinusitis symptoms
    Symptoms that never occur with acute bacterial sinusitis:
    clear runny nose, being severely ill
    Urgency:
    Primary care doctor
  10. 10.Normal Variation of Constipation

    Constipation is a very common condition affecting the large intestine. It is characterized by difficulty passing stool, or passing stool less often. Commonly it is linked to not eating enough dietary fiber, not drinking enough fluids, or not getting enough exercise. Some medications can cause constipation as well.

    For the short term, an over-the-counter laxative can help with your constipation. You can try to make changes at home to help prevent these symptoms. Dietary changes are typically effective: drink more fluids and eat more fiber (found in bran, root vegetables, nuts, and whole-grain flour). There are also over-the-counter fiber tablets that can help increase your dietary fiber.

    Rarity:
    Common
    Top Symptoms:
    abdominal pain (stomach ache), nausea, stomach bloating, constipation, abdominal cramps (stomach cramps)
    Symptoms that always occur with normal variation of constipation:
    constipation
    Symptoms that never occur with normal variation of constipation:
    vomiting
    Urgency:
    Self-treatment
