FluFlu is one of the most common conditions that can weaken our health. According to the World Health Organization, the FluFlu is a viral condition that mainly affects the nose, throat, bronchial tubes, and lungs and that generally can last up to a week, manifesting itself through symptoms such as fever, rhinitis, headache, muscle aches, malaise, cough, and sore throat.

FluFlu is a widespread illness because it spreads easily, and most affected people recover very quickly without problems. However, there are some cases in which the FluFlu can become complicated and further compromise the health of the person or trigger other pathologies. To know when to go to the doctor for the FluFlu, we invite you to continue reading this FastlyHealarticle that we have prepared for you.

¿ FluFlu or cold?

To know when to go to the doctor for the FluFlu, it is necessary to learn to differentiate this condition from a common cold. The cold begins with a runny nose, cough, and general malaise, while the FluFlu begins suddenly and suddenly with a very severe headache, body aches, and a fever of 39ºC.

The FluFlu can cause more complications than the common cold, and it also takes much longer to disappear; for this reason, when a person has more than two weeks with the FluFlu, the symptoms do not improve, and the discomfort is persistent; it is necessary to consult a medical specialist to avoid that the FluFlu could become a more severe condition.

When to go to the doctor for a cold

It would help if you went to the doctor for a cold when:

  • You have a fever exceeding 38 degrees.
  • Severe coughing fits.
  • The duration of the cold exceeds ten days.
  • When you cough, you get to spit up green, yellow, brown, or rust-colored mucus.
  • You have breathing difficulties and notice “whistles” in your chest.
  • Chest pain.
  • Headache increases.
  • After several days, the nasal congestion continues.
  • You start with a small earache that gradually lasts more than 24 hours. Sometimes the pain is very, very intense. If you suddenly suffer severe pain that lasts more than an hour, it is best to see your regular doctor.
  • The sore throat does not stop and lasts for more than 3 or 4 days.

Evolution of the Flu in the body

Knowing the process of action that this virus has in the body is necessary to determine when something goes wrong or when to go to the doctor for the FluFlu. The first symptom of the FluFlu that appears suddenly is fever above 38ºC, which is followed by common manifestations such as:

  • Dizziness
  • Body pain.
  • I am shaking chills.
  • Headache.
  • Decay.
  • Sickness.

Fever and muscle aches usually begin to improve from the second or fourth day, but also at this stage; the body may experience other kinds of discomfort that can include symptoms such as:

  • Dry cough.
  • Difficulty breathing.
  • Throat pain.
  • Rhinorrhea and sneezing.

It’s essential to pay attention to:

  • The majority of the symptoms disappear after seven days . Find out exactly how long the Flu lasts in the following article.
  • Coughing and feeling tired are manifestations that can take weeks to disappear.
  • Some people lose their appetite when they have the Flu.
  • The fever may appear after the fourth day.
  • The FluFlu that lasts more than two weeks is not regular.

When to go to the doctor for the FluFlu

  • The high fever persists for more than five days and does not respond to treatment.
  • When symptoms do not improve after four days and do not respond to treatment.
  • When the cough is accompanied by wheezing and shortness of breath.
  • When the skin looks purple.
  • When a very high fever and earache accompany the discomfort.
  • When the FluFlu is accompanied by green or yellow phlegm, the person perceives a lot of pain in the chest when coughing.
  • When fever is accompanied by earache, dizziness, and pressure on the cheeks, eyes, and jaw.
  • When there is the presence of pus or deposits banks in the tonsils.
  • Symptoms improve and then come back stronger.

There are certain people who, in the event of any flu development, should see a doctor preserve their health and avoid complications from pre-existing diseases. Some of these cases are:

  • Pregnant women.
  • People over 60 years.
  • Children, adults, and the elderly with pre-existing illnesses that can be complicated by the FluFlu, such as asthma, heart disease, kidney disease, diabetes, multiple sclerosis, or AIDS.

Complications of the Flu

When it is necessary to go to the doctor for the FluFlu, but this recommendation is ignored, the person can considerably compromise their health, being able to present essential complications that can even cause death. The primary complications of the FluFlu are:


It can be spread by viruses, bacteria, and fungi and severely compromises the respiratory condition of people. It is characterized by coughing up green or yellow phlegm. In our article pneumonia: causes, symptoms, and treatment we explain more about this condition.


It is the inflammation of the brain due to viral infections. It begins with a fever, weakness, and headache, so it is sometimes mistaken for the FluFlu.

Bacterial meningitis

Bacterial meningitis is a severe bacterial infection of the membranes surrounding the brain and spinal cord WHO states that this disease is fatal in 50% of untreated cases.


When the fever is very high and does not respond to treatment, the person increases the risk of seizures if the temperature level is not controlled in time.

Get a flu shot

An alternative to reduce the chances of getting the FluFlu and avoiding both complications and a visit to the doctor is to get vaccinated against the FluFlu. The flu vaccine allows protecting the body from the different mutations of the flu virus to prevent it from spreading; for this reason, it is recommended to apply it every year to strengthen the immune system against any changes that the virus may present.

Anyone is a candidate for a flu vaccine. Still, this prevention is even more recommended for pregnant women, children, people with autoimmune diseases, over 60, doctors and nurses constantly surrounded by viruses and bacteria, and people with diabetes or a depressed immune system.

Why do you have to vaccinate every year? The flu virus mutates all the time, so it is necessary to adjust the vaccine every year to remain efficient against the viral mutation. To find out that the virus mutated, the WHO established an alert system more than 50 years ago that monitors influenza viruses worldwide to recognize when changes have occurred. The flu vaccine begins to take effect two weeks after the injection and lasts for one year.
