Understanding Signs and Symptoms

When it comes to health and diagnosis, terms like signs and symptoms are frequently used, yet they hold distinctly different meanings. Understanding these differences can empower patients and enhance communication with healthcare professionals, ultimately leading to more effective treatment and management.

A sign is an observable effect of a health condition, noticed by a physician, while a symptom is an effect felt and reported only by the person experiencing it.This post delves briefly into the key distinctions between signs and symptoms, why they’re important, and how they shape the diagnostic process.

Why Signs And Symptoms Matter in Health

Signs

Objective Indicators Observed By Health-Care Professionals

A sign is an observable, measurable indication of a health or medical condition, easily detected by healthcare professionals. Unlike symptoms, which are subjective, signs are typically physical findings or quantifiable data obtained through physical exams, tests, X-ray, CT scan, or other diagnostic tools. For instance:

Skin Rash
A red skin rash might indicate a fungal infection, such as ringworm, eczema, or psoriasis.
Watery Eyes and Sneezing
A healthcare provider may observe itching, nose rubbing, sneezing, or eye watering as signs of chronic sinusitis.
Broken Bone
An X-ray can reveal more, allowing assessment and proper treatment of breaks and fractures.
Scratching the Ear
Rubbing or scratching the ear can be due to a fungal infection of the ear.
Vomiting
A pregnant woman who vomits may be suffering from the nausea caused by her morning sickness.

Vital Signs

Certain signs, such as vital signs—including heart rate, blood pressure, and respiration rate—are closely monitored in medical settings, especially during procedures or in critical care. Vital signs serve as foundational markers of health, as they provide immediate insights into a person’s physiological state and are crucial for evaluating responses to treatment.

Why Signs Matter

Signs are often the first clues that signal a health issue, and many can be measured or quantified. This objectivity allows healthcare providers to track progress over time and assess the effectiveness of treatment.

For example, a high fever can be precisely measured, helping to determine the presence of an infection and monitor its response to medication.

Abdominal bloating – Visibly swollen or distended abdomen, seen in SIBO and IBS.
Anemia (blood tests) – More common in IBD, where chronic inflammation or malabsorption affects red blood cell production. Patients can also have bleeding from the bowel.
Elevated C-reactive protein (CRP) – A blood marker indicating inflammation.
Erythema (redness) around the anus – Can be seen in IBD and Candida overgrowth in children.
Positive breath test for hydrogen/methane – Diagnostic sign for SIBO, showing excess gas production.
Presence of inflammatory cells in stool – Detectable in stool analysis, indicating inflammation often related to IBD.
Rectal bleeding – Typically associated with IBD, especially in conditions like ulcerative colitis.
Thickened intestinal wall on imaging – Found in IBD through imaging studies such as CT or MRI.
Weight loss – Notable in advanced IBD or chronic Candida, where malabsorption might occur.
White coating on the tongue – Common sign of oral Candida overgrowth.

Symptoms

Subjective Experiences Reported by Patients

In contrast, a symptom is a subjective experience that cannot be measured or observed directly by anyone other than the patient.

Symptoms reflect what the patient feels, notices, or experiences. Some common symptoms include:

Pain, fatigue, nausea, and dizziness
Digestive issues, such as cramps or bloating
Neurological symptoms like brain fog or headaches

Because symptoms are subjective, they often vary significantly between individuals. For example, one person’s description of a headache might differ greatly from another’s, making it essential for patients to describe their experiences accurately to assist with diagnosis.

Types of Symptoms

Interestingly, symptoms can be categorised based on their duration and pattern:

Acute Symptoms:
These develop suddenly and typically last a short period. Examples include a headache or a stomach upset after eating something questionable.
Chronic Symptoms:
These persist over an extended period, often recurring in the same form. Conditions like arthritis or fibromyalgia are characterised by chronic symptoms.
Relapsing Symptoms:
These are symptoms that disappear for a while but eventually return. Conditions like eczema often present relapsing symptoms that flare up and then subside.
Remitting Symptoms:
These improve or resolve with time, sometimes completely. Certain autoimmune disorders, like multiple sclerosis, exhibit remitting symptoms, where symptoms lessen or disappear before potentially recurring.

Abdominal pain or cramping – Common in IBS, IBD, and SIBO, often worse after eating.
Bloating – Minor bloating is commonly experienced by many with SIBO, IBS and Candida.
Brain fog – Reported by people with Candida overgrowth and SIBO, likely due to gut-brain axis interactions.
Constipation – Seen in IBS-C (constipation-type IBS) and sometimes in Candida overgrowth.
Fatigue – Frequently reported in Candida overgrowth, IBD, and SIBO due to malabsorption and chronic inflammation.
Frequent diarrhoea – Common in IBS-D (diarrhea-predominant IBS), IBD, and SIBO.
Gas – Common in SIBO, IBS, and Candida overgrowth, often leading to discomfort and fullness.
Joint pain – A symptom that can be associated with both IBD and Candida overgrowth, potentially due to systemic inflammation.
Nausea – Often reported by those with IBS, IBD, and SIBO, especially after meals.
Sugar cravings – Frequently reported in Candida overgrowth, as Candida thrives on sugars.
Urgent bowel movements – A symptom of IBD and IBS, patients feel a need to pass stool urgently.

Diagnosing And Treating Based on Signs and Symptoms

Going Beyond Testing and Observation

While signs and symptoms are essential for understanding health concerns, they often don’t reveal the full story. For instance, diagnosing Candida based solely on a white tongue or digestive discomfort is limited and may lead to incomplete treatment.

Effective diagnosis and treatment generally require going beyond visible signs and subjective symptoms to uncover deeper root causes and contributing factors.

Addressing the underlying cause of symptoms is especially critical with chronic or relapsing conditions. Symptom-focused treatments might offer temporary relief, but for lasting improvement, it’s crucial to explore and address the core issues, like diet, stress, and lifestyle habits, that might be fueling the condition. For example, diet plays a substantial role in gut-related issues like Candida or Small Intestinal Bacterial Overgrowth (SIBO). High-sugar or processed foods can exacerbate these conditions, while dietary modifications can reduce flare-ups and support healing.

The Importance of Distinguishing Between Signs and Symptoms

Understanding the difference between signs (objective, observable evidence of disease) and symptoms (subjective experiences reported by the patient) is more than just a medical technicality—it can be transformative for your health journey. Recognising patterns in both signs and symptoms can help identify lifestyle triggers, dietary habits, and environmental factors that might be worsening your condition.

Health is multifaceted and unique to each individual, so learning to tune into your own signs and symptoms can empower you to collaborate more effectively with your healthcare provider. This pro-active approach can lead to a more accurate diagnosis and a comprehensive treatment plan that addresses the full picture of your health, and give more lasting results.

Key Points to Remember

Look for Patterns:
Notice recurring signs and symptoms to help pinpoint lifestyle or dietary contributors.
Prioritise Root Causes:
Aim for treatments that address underlying issues rather than just managing symptoms.
Track Changes:
Keep a health journal to record symptoms, food intake, and lifestyle changes for greater clarity.
Empower Yourself:
Use knowledge to advocate for a thorough, holistic treatment plan.
