Influenza Symptoms: When to See a Doctor

Influenza, or flu, usually arrives all at once. One moment you feel fine, and a few hours later you have a fever, aching muscles, and no energy at all.

Most healthy adults are back to normal in about a week. Flu circulates in Indonesia year-round and picks up at certain times, so it is worth knowing which symptoms you can manage at home and which ones mean it is time to see a doctor.

If breathing becomes difficult, or there is chest pain, treat it as an emergency and go straight to the nearest emergency department.

Common Symptoms of Influenza

Flu tends to hit harder and faster than a common cold. The usual signs are:

• A sudden fever, often above 38°C, with chills
• A cough, sore throat, and a runny or blocked nose
• Headache, plus aching muscles and joints
• Feeling drained, sometimes too weak to get out of bed
• Vomiting or diarrhea, which happens more often in children

Symptoms usually peak in the first few days and ease off over the following week. A cough and tiredness can linger a little longer, and that on its own is not a cause for concern.

When Flu Symptoms Need a Doctor

Book a consultation if your symptoms have not started to improve after three to five days, or if they get better and then turn worse again. Some people should see a doctor earlier, even with mild symptoms, because flu can hit them harder:

• Pregnant women
• Older adults
• Babies and young children
• Anyone with asthma, diabetes, heart disease, or lung disease
• Anyone with a weakened immune system

If you are in one of these groups, do not wait out the fever at home. An early check means treatment can start before complications such as pneumonia have a chance to develop.

Warning Signs That Need Urgent Care

Go to the nearest puskesmas, clinic, or hospital emergency department right away if you or someone you are caring for has:

• A high fever that will not come down after more than three days
• Shortness of breath or fast breathing, or in a child, the chest pulling in with each breath
• Chest pain or pressure
• Severe weakness, seizures, confusion, or trouble waking up
• Signs of dehydration: unable to drink, passing very little urine, or bluish lips or face

These symptoms need care the same day, not an appointment next week. The emergency department at Bali International Hospital is open 24 hours on 150 919 in Indonesia, or ( 62) 21 3002 0031 from overseas.

Caring for Yourself at Home

For a straightforward case of flu, most of the work is rest:

• Sleep as much as your body asks for, and drink fluids through the day
• Take paracetamol as directed for fever or aches
• Skip antibiotics unless a doctor prescribes them, since they do not work on flu viruses
• Wear a mask and keep your distance from babies, elderly relatives, and anyone with a chronic illness

Vaccination and Antiviral Treatment

An annual flu vaccination is the most effective way to lower your risk, and it matters most for the groups listed above:

• Pregnant women
• Older adults
• Young children
• Anyone living with a long-term condition

Protection builds over about two weeks and fades across the year, which is why the vaccine is repeated annually. If the flu is diagnosed early, your doctor may prescribe an antiviral medicine.

Antivirals work best when started within the first two days of symptoms, and they are usually reserved for people at higher risk of complications. They do not replace vaccination, and most healthy adults do not need them.

Get Checked Before Flu Sets You Back

Most flu clears up on its own. The point of seeing a doctor is to catch the small number of cases that do not, particularly in children, older adults, and anyone with a long-term condition.
