Sepsis: the emergency many people have never heard of

Key points#

• Sepsis is the body's extreme, self-damaging response to an infection, and it is a life-threatening emergency.
• Warning signs include confusion, extreme pain or discomfort, fever or shivering or feeling very cold, shortness of breath, a high heart rate, and clammy skin.
• Seek emergency care immediately and say you are concerned about sepsis; earlier treatment saves lives.
• Anyone with an infection can develop sepsis, with higher risk in the very young, older adults, and people with weakened immune systems.

There is an emergency that sends a great many people to hospital each year, that can develop from an ordinary infection, and that a surprising number of people cannot name or describe. It is sepsis. The gap between how common and serious sepsis is, and how little it is recognized by the public, is exactly why it is worth learning about. Knowing what sepsis is and how it announces itself is the kind of awareness that occasionally saves a life.

What sepsis is#

Sepsis is the body's extreme response to an infection. Normally, when the body fights an infection, the response stays targeted and contained. In sepsis, that response goes into overdrive and begins to injure the body's own tissues and organs. Left unchecked, it can lead to organ failure and become life-threatening with alarming speed.

The part people miss is where sepsis comes from. It does not require an exotic or dramatic infection. It can develop from common ones, a chest infection, a urinary infection, a skin infection, and that is part of why awareness matters for everyone. Sepsis is not the infection itself but the body's dangerous reaction to it.

The warning signs#

Because sepsis can follow an ordinary infection, the key is noticing when someone is far sicker than the infection alone would explain. The warning signs to know include:

• Confusion, disorientation, or unusual drowsiness.
• Extreme pain or discomfort, a feeling of being more unwell than ever before.
• Fever, shivering, or feeling very cold.
• Shortness of breath or fast breathing.
• A high heart rate.
• Clammy, sweaty, or mottled skin.

No single sign is unique to sepsis, but the overall picture, someone with an infection who becomes confused, very unwell, breathless, or whose skin and heart rate change, is the pattern to act on. In young children, additional concerning signs include being abnormally sleepy or difficult to wake, breathing very fast, or having a rash that does not fade. Trust the instinct that someone is seriously and unusually unwell.

Why speed matters#

Sepsis shares with stroke and heart attack the quality that makes those emergencies so urgent: it is treated far more successfully the earlier it is caught. As sepsis progresses, the risk to the body's organs rises, so the window in which treatment works best is early. Prompt recognition and prompt care are the levers that change outcomes.

This is the entire reason for raising awareness. Many of the lives lost to sepsis are lost partly to delay, and delay often comes from not recognizing that an infection has turned into something far more dangerous. Closing that recognition gap is something ordinary knowledge can do.

What to do#

If you suspect sepsis, the response is straightforward and it is urgent. Seek emergency care immediately, and when you do, say clearly that you are concerned about sepsis. Naming it matters, because it can prompt the rapid assessment that sepsis needs. This is not a situation for waiting to see if things improve overnight or for a routine appointment in a few days. When someone with an infection becomes seriously and unusually unwell, treat it as the emergency it may be.

It is also worth knowing who is most at risk, not to exclude anyone, but to raise vigilance. Very young children, older adults, people with weakened immune systems, and those with chronic illnesses are at higher risk. But because sepsis can affect anyone with an infection, the awareness belongs to everyone.

When an infection turns dangerous#

Add sepsis to the short list of emergencies you can recognize. Remember that it is the body's dangerous response to an infection, that it can follow common infections, and that its warning signs, confusion, extreme illness, fever or feeling very cold, breathlessness, a racing heart, and clammy skin, mean someone is far more unwell than the infection alone would explain. If you see that pattern, seek emergency care right away and say the word sepsis. Most people never need this knowledge, but for the ones who do, recognizing sepsis early is among the most valuable things a bystander or family member can possibly do.
