Psychosomatic Manifestations: When the Mind Speaks Through the Body
Psychosomatic manifestations are real physical symptoms with psychological causation. Psychiatrist Paschalis Gkikas assesses and treats psychosomatic disorders with an integrated approach in Athens.
Psychosomatic Manifestations: When the Mind Speaks Through the Body
Pain that is not explained by tests. Fatigue that does not improve with rest. Gastrointestinal symptoms without an organic cause. Psychosomatic manifestations (ICD-10: F45) are among the most underdiagnosed and least understood groups in modern medicine. They do not mean that the patient is “imagining” symptoms — they mean that psychological distress is expressed in the body through biologically measurable mechanisms.
What are psychosomatic manifestations?
The term “psychosomatic” does not mean “imaginary”. It means that psychological factors — stress, trauma, suppressed emotion, chronic anxiety — lead to real, measurable changes in the body.
In ICD-10, category F45 includes:
- Somatization disorder (F45.0): Multiple physical symptoms across multiple systems
- Undifferentiated somatoform disorder (F45.1)
- Hypochondriasis (F45.2): Persistent belief of serious illness
- Somatoform autonomic dysfunction (F45.3): Heart, gastrointestinal and respiratory systems
- Persistent somatoform pain disorder (F45.4)
- Dissociative / conversion disorders (F44): Neurological symptoms without a neurological cause
Clinical presentation and symptoms
Musculoskeletal
- Chronic pain involving the head, back, neck or joints
- Muscle tension that does not improve with analgesics
- Fibromyalgia syndrome, a common psychosomatic entity
Gastrointestinal
- Irritable bowel syndrome (IBS), strongly linked to anxiety and depression
- Nausea, difficulty swallowing, bloating without an organic cause
- Functional dyspepsia
Cardiovascular / respiratory
- Palpitations, chest discomfort without a cardiological cause
- Shortness of breath, sensation of a “tight throat”
- Hyperventilation syndrome
Neurological
- Tension headache, migraine with psychogenic triggers
- Dizziness, sense of derealization
- Tremor, paresthesias, visual changes without a neurological substrate
Neurobiological basis
The psychosomatic connection now has clear neurobiological foundations:
- HPA axis (hypothalamus–pituitary–adrenal axis): Chronic stress leads to pathological cortisol secretion, which regulates immune response, inflammation and neural sensitivity.
- Neuro-immune connection: Psychological distress activates inflammatory cytokines, such as IL-6 and TNF-α — the same pathways involved in chronic pain, fatigue and depression.
- Gut-brain axis: The enteric nervous system communicates directly with the brain through the vagus nerve. Anxiety changes the gut microbiome and vice versa.
- Central sensitization: In chronic stress or trauma, the CNS is “recalibrated” toward increased pain sensitivity.
Treatment approach
Psychosomatic disorder is not treated with one medication or one therapy. It requires coordination of psychiatric assessment, psychotherapy, neuromodulation when required, and patient education.
Pharmacological treatment
- SSRIs / SNRIs: Effective in psychosomatic pain, IBS, fatigue and coexisting depression or anxiety.
- Low-dose amitriptyline: A classic option for chronic pain and tension headache.
- Pregabalin / duloxetine: For fibromyalgia and neuropathic pain.
Psychotherapy
Cognitive Behavioral Therapy (CBT) is the most studied intervention — it identifies the connection between thoughts, emotions and bodily sensations.
rTMS in psychosomatic manifestations
In chronic pain of psychosomatic origin, studies show that targeting the DLPFC or motor cortex may reduce central sensitization and improve the pain threshold.
Frequently asked questions (FAQ)
If my tests are normal, does that mean I have no problem?
Absolutely not. Normal tests mean absence of findings in the specific organic systems tested — not absence of dysfunction. Central sensitization and the neurobiological changes of stress are not visible in blood tests or imaging studies.
Does psychosomatic mean that I am “thinking up” the symptoms?
No. It means that psychological factors reproduce real, biologically measurable changes in the body. Pain, fatigue and gastrointestinal discomfort are just as real as symptoms with an organic cause.
Can stress cause physical symptoms?
Yes — and this is neurobiologically documented. The HPA axis, inflammatory cytokines and the gut-brain axis are biological pathways through which stress becomes body.
Do I need a psychiatrist or a psychologist?
Often both. The psychiatrist assesses and manages the pharmacological dimension and coexisting psychiatric disorders. The psychologist undertakes the psychotherapeutic intervention.
