We often think of immunity only as the ability to avoid getting ill during autumn and winter. In reality, the immune system has a much broader role. It helps the body recognise what belongs to it and what may pose a threat. It responds to infections, supports tissue repair and healing, and interacts with many other body systems.

If you experience frequent cystitis after getting cold, recurrent thrush, herpes flare-ups, persistent fatigue or the feeling that you catch every infection, it may be worth discussing possible contributing factors with a doctor. Frequent illness can have different causes and requires an individual assessment.

Hormonal balance and immune response

Sex hormones can influence immune activity. Changes in oestrogen and progesterone levels may affect inflammatory processes, the condition of mucous membranes and susceptibility to certain infections.

For example, recurrent candidiasis or bacterial vaginosis may be associated with several factors, including hormonal changes, diabetes, medication use, immune conditions or changes in the vaginal microbiome. They are not always simply a matter of hygiene. Identifying the cause is important for choosing the right treatment and prevention plan.

The gut and immune health

A significant part of the immune system is associated with the gastrointestinal tract. Digestive health, nutrition and the gut microbiome can all influence immune function.

Digestive symptoms, restrictive diets or conditions that affect nutrient absorption may contribute to nutrient deficiencies and overall inflammation. The gut also plays a role in the metabolism and elimination of hormones, including oestrogen. This is why digestive health can be relevant when assessing both immune and gynaecological concerns.

Stress and recovery

In the short term, stress can help the body respond to challenges. However, prolonged stress, poor sleep and constant overexertion may affect immune regulation, recovery and overall wellbeing.

After a difficult emotional period, chronic lack of sleep or prolonged workload, some people notice that infections recur more often or that recovery takes longer. Supporting the nervous system, sleep and a sustainable daily routine can be an important part of maintaining health.

Nutrient deficiencies

Vitamin D, iron, zinc, protein and other nutrients are involved in normal immune function. However, supplements should not be prescribed “by default”. Their necessity, form and dosage depend on your symptoms, medical history, diet, medications and, where appropriate, test results.

Taking high doses of supplements without assessment may be ineffective or harmful. A personalised approach helps identify what your body may actually need.

Immune health is about balance

When working with patients who experience frequent infections, chronic inflammation or ongoing fatigue, I do not rely on one universal protocol. We look at the whole picture: symptoms, hormonal health, nutrition, digestion, stress, sleep and possible nutrient deficiencies.

Supporting immunity is not about “boosting” it with one product. It is about helping the body restore balance and maintain its natural protective functions.
