Stress and physical symptoms

When stress shows up in the body

Not everyone under prolonged load recognises it as such. For many the first signal is neither a thought nor an emotion: it is a bodily symptom that appears, stays, and finds no explanation.

It is one of the reasons the path almost always begins with a doctor rather than a psychologist. Which is correct: that is the right place to start.

The most frequent forms

Gastrointestinal difficulties — pain, bloating, changes in bowel habit. Tension headache, with its characteristic band around the head. Chronic muscular tension in the neck, shoulders and jaw, often with night-time bruxism.

Then tiredness that does not respond to rest, disrupted sleep, and sometimes skin manifestations or an increased frequency of minor infections.

What these pictures share is their generic quality: they are compatible with a great many things, which is exactly why they need ruling out by examination first.

Why the body responds this way

The stress response is useful and designed to be brief: the system activates, meets the demand, and returns to baseline. The problem is not the activation — it is its duration.

When the demand does not end, the return to baseline never fully happens. Activation becomes the new normal, and the systems that pay for it are the ones depending on fine regulation: digestion, sleep, muscular tension, immune defences.

Medical assessment comes first

Always, without exception. Thyroid conditions, anaemia, deficiencies, coeliac disease and various inflammatory conditions produce pictures of fatigue and somatic symptoms that overlap closely with stress-related ones.

Attributing a symptom to stress before the indicated investigations have been done is a mistake that costs time, and sometimes more than that. The first reference point is a family doctor, who decides which tests are needed.

It is not the same as health anxiety

These are two different pictures and they are often confused. In health anxiety the centre is the fear of having a serious illness, and symptoms — which may be mild or absent — get read as evidence; the typical behaviour is checking and seeking reassurance.

Here the symptoms are present, continuous and disruptive to daily life, and the main worry is not a feared diagnosis but the fact of feeling unwell without understanding why.

The distinction matters, because the work differs: there the intervention is on the checking loop, here on the load and its regulation.

How the work goes

Alongside the medical path, never instead of it. We start by mapping the relationship between symptoms and context: when they appear, what precedes them, what eases them — information that usually only emerges by writing it down, because memory loses it.

Then the work is on reducing the load where it can be reduced, on recovery — which is a physiological condition, not a reward to be earned — and on the loop between symptom and worry, which once running adds activation to an already activated system.
