When Should I Speak to My GP Instead? 

In the UK, the General Practitioner (GP) acts as the first point of contact for the vast majority of non-emergency health concerns. While many minor ailments can be managed with rest or over-the-counter advice from a pharmacist, knowing when to transition to a formal GP consultation is vital for early diagnosis and long-term health. High blood pressure, for instance, is a condition that rarely presents with symptoms but requires a GP’s oversight to prevent serious complications. This article outlines the specific signs that suggest you should speak to your GP instead of continuing with self-care, ensuring you receive the right level of medical attention at the right time.

When to Seek a GP Consultation for Ongoing Health Concerns? 

You should speak to your GP if you have persistent symptoms that do not improve with self-care, or if you are concerned about a new, unexplained physical or mental health change. In the context of blood pressure, you should book an appointment if your home monitor consistently shows readings above 135/85 mmHg. Your GP is responsible for diagnosing chronic conditions, ordering blood tests, and coordinating specialist referrals. 

While pharmacists can offer advice on minor illnesses like coughs or colds, a GP is necessary when symptoms are ‘atypical’ meaning they don’t follow the usual pattern or if you have a family history of a specific condition. A GP consultation allows for a comprehensive review of your medical history, which is essential for determining whether a symptom is an isolated issue or part of a wider health trend. 

Identifying ‘Red Flag’ Symptoms for Your GP 

A ‘red flag’ is a symptom that may not be an immediate 999 emergency but requires a professional clinical review as soon as possible. These symptoms often indicate that an underlying process needs investigation through diagnostic tests such as blood work, imaging, or physical examination. Ignoring these signs can lead to delayed treatment for conditions that are more easily managed when caught early. 

According to NHS and NICE guidance, you should contact your GP if you notice: 

• Unexplained Weight Loss: Losing weight without trying can be a sign of various metabolic or inflammatory issues. 

• Persistent Changes in Bowel Habits: Any change lasting more than three weeks should be reviewed. 

• New Lumps or Swellings: Especially those that are painless, firm, or increasing in size. 

• Persistent Fatigue: Tiredness that does not improve with rest and interferes with daily life. 

• Consistently High Blood Pressure: Readings that remain elevated during home monitoring even when you are relaxed. 

The GP’s Role in Managing Blood Pressure 

If you have been monitoring your blood pressure at home and notice that your numbers are frequently in the ‘high’ range, your GP is the person who will confirm a diagnosis. They will use clinical tools such as Ambulatory Blood Pressure Monitoring (ABPM) to ensure your readings are accurate and not influenced by the ‘white coat’ effect. 

During this process, the GP will: 

• Review your QRISK score: This calculates your 10-year risk of a heart attack or stroke. 

• Order blood tests: To check your cholesterol levels and kidney function. 

• Check for organ damage: This may include an eye exam or a urine test to look for protein. 

• Discuss management: Determining if lifestyle changes are sufficient or if medication is required. 

Causes for a GP Consultation 

Most GP visits are prompted by symptoms that have a ‘primary’ cause, such as lifestyle factors or age-related changes. However, a GP is also trained to look for ‘secondary’ causes underlying medical issues that manifest as common symptoms. Distinguishing between these requires the diagnostic expertise found in a primary care setting. 

Common reasons to transition from self-monitoring to a GP visit include: 

• Atypical Pain: Pain that is persistent, recurring, or worsening over time. 

• Medication Side Effects: If you are struggling with side effects from a current prescription. 

• Family History Concerns: If a close relative is diagnosed with a hereditary condition, such as early-onset hypertension. 

• Mental Health Support: If you are experiencing persistent low mood, anxiety, or sleep disturbances that affect your quality of life. 

Triggers That Require Medical Review 

Certain environmental or lifestyle triggers can cause a shift in your health that requires a GP’s intervention. While some triggers cause temporary changes, others can unmask a dormant health condition. If you notice a significant change in your health following a specific event or lifestyle shift, a GP can help determine if the response is normal or requires treatment. 

Specific triggers to discuss with your GP include: 

• Stress and Burnout: When emotional stress begins to manifest as physical symptoms like headaches or palpitations. 

• New Medication or Supplements: If you notice changes after starting a new over-the-counter remedy or herbal supplement. 

• Major Lifestyle Changes: Significant changes in diet or activity levels that coincide with new physical sensations. 

• Recovery from Illness: If you are not returning to your baseline health after a common virus or infection. 

Primary vs. Secondary Health Concerns 

UK General Practice focuses on differentiating between primary issues (the condition itself) and secondary issues (symptoms caused by a different underlying problem). This differentiation is why your GP may ask questions that seem unrelated to your main complaint they are checking for hidden causes. 

Feature	Primary Health Concern	Secondary Health Concern
Example	Essential Hypertension (Age/Lifestyle)	Hypertension caused by Kidney Disease
GP Focus	Long-term management and risk reduction	Identifying and treating the hidden cause
Diagnostic Pathway	Monitoring and lifestyle review	Blood tests, scans, and specialist referral
Outcome	Controlled through habit and/or meds	May resolve if the underlying cause is fixed

Conclusion 

Knowing when to speak to your GP is an essential part of maintaining your health. While self-care and pharmacy advice are valuable for minor, short-term issues, any symptom that is persistent, unexplained, or relates to high blood pressure readings should be reviewed by a professional. Your GP provides the diagnostic expertise needed to ensure you receive an accurate assessment and a safe management plan. 

If you experience severe, sudden, or worsening symptoms such as chest pain, a sudden change in vision, or a severe headache, call 999 immediately.
