Identifying Underlying Conditions: A Guide for Patients and Caregivers

Why finding the underlying cause matters

When you or someone you care for has ongoing symptoms, finding the root cause can improve treatment choices and outcomes. Many symptoms such as fatigue, pain, or shortness of breath can come from different conditions. A clear plan that combines history, exam, and the right tests helps your care team narrow the possibilities and guide next steps.

What to share at your appointment

Track symptoms clearly

Keep a simple diary that notes

  • What the symptom feels like and where it is
  • When it started, how often it happens, and how long it lasts
  • What makes it better or worse
  • Any impact on sleep, mood, or daily activities

Bring this record to each visit. Clear timelines help your clinician connect patterns and choose the most useful tests.

List all medicines and supplements

Write down every prescription, over the counter medicine, vitamin, and herbal product you take. Include doses and how often you use them. Some symptoms are caused or worsened by side effects or interactions. If you notice a new symptom after starting a medicine, record the date and tell your clinician.

Document personal and family history

Include prior conditions, surgeries, allergies, and exposures at work or home. Add a family tree with major diagnoses and ages at diagnosis when known. Family health history can reveal patterns that raise or lower the chance of specific conditions and can guide screening and referrals.

What your clinician may do

History and physical exam

Your clinician will ask detailed questions and perform a head to toe exam. Findings from this step point to likely causes and help avoid unnecessary testing. Expect questions about onset, severity, triggers, travel, infections, sleep, mood, and daily function.

Common initial tests

Your plan may include one or more of the following

  • Blood tests such as complete blood count to check red and white blood cells and platelets, metabolic panel to assess kidney, liver, and electrolyte status, thyroid tests such as TSH and related hormones, and A1C to screen for diabetes
  • Urinalysis to look for infection, blood, or protein
  • Electrocardiogram for heart rhythm when symptoms suggest a cardiac cause
  • Stool tests or other targeted labs based on your history and exam

Results are interpreted together with your story and exam. One test rarely explains everything. Your clinician may repeat a test or use a different method to confirm a finding.

Imaging and other tests

Imaging is ordered when it is likely to change care, based on symptoms and exam. Options include X ray, ultrasound, CT, MRI, and others. Some conditions require nerve testing, sleep studies, or endoscopy. Your team should explain why a test is needed, what it can and cannot show, and what the next steps will be after the result.

When urgent symptoms need emergency care

Call 911 now if you notice any of the following

  • Signs of possible stroke such as sudden weakness or numbness on one side, sudden trouble speaking or understanding, sudden trouble seeing, sudden trouble walking, or a sudden severe headache with no known cause
  • Signs of possible heart attack such as chest pressure or pain that may spread to the arm, back, neck, or jaw, shortness of breath, breaking out in a cold sweat, nausea, or lightheadedness

Do not drive yourself. Fast action saves brain and heart tissue and improves outcomes.

Working with specialists and getting a second opinion

When to consider genetic counseling

Consider genetic counseling when a condition runs in the family, when you or your child has features that suggest a genetic condition, or when you are planning a pregnancy and have questions about inherited risks. A genetics professional can review your family history, explain testing options, and support informed choices.

Navigating common scenarios

Fatigue

Fatigue can come from anemia, thyroid disease, sleep disorders, infections, mood disorders, medication effects, or chronic conditions. Clues include heavy menstrual bleeding, snoring or witnessed apneas, weight change, heat or cold intolerance, sadness or loss of interest, and recent medication changes. Your clinician may order blood counts, iron studies, thyroid tests, A1C, and sleep evaluation when indicated.

Numbness or tingling

Numbness or tingling can result from diabetes, vitamin deficiencies, nerve compression, autoimmune disease, or medication effects. Your evaluation may include blood sugar testing, vitamin B12 and related labs, a neurologic exam, and nerve studies when appropriate. Report any sudden weakness, severe back pain with new bladder or bowel problems, or numbness spreading quickly, which needs urgent care.

Sleep problems

Loud snoring, pauses in breathing during sleep, and daytime sleepiness can signal sleep apnea. Diagnosis usually requires a sleep study at home or in a lab. Treating sleep apnea can improve blood pressure, mood, and energy, and reduces risks for the heart and brain.

How caregivers can help

Caregivers play a vital role in preparing information, sharing observations the patient may not notice, and supporting follow through on testing and treatment plans.Bring a short list of top questions, take notes during visits, and ask for a clear summary of the plan before you leave.If instructions are not clear, ask for plain language and written steps.

Prepare and partner for safer diagnosis

  • Before the visit, gather your symptom diary, medicine list, and family history
  • During the visit, ask what the most likely causes are, what the clinician is ruling out, which test is first and why, and when to follow up
  • After the visit, review results in your portal, ask about any unexpected or concerning results, and confirm how you will be contacted and what to do if symptoms change

If you experience a serious side effect from a medicine or device, tell your clinician and report it through the appropriate safety program. You can also ask your pharmacist for help understanding side effects and interactions.

FAQ: Finding the underlying cause of symptoms

  • Why does finding the underlying cause matter?
    Many symptoms like fatigue, pain, or shortness of breath can come from very different conditions. Finding the root cause helps your care team choose the right tests, avoid unnecessary ones, and match treatment to what is really going on, which can improve outcomes and safety.
  • What should I track in a symptom diary?
    Write down what the symptom feels like and where it is, when it started, how often it happens, how long it lasts, what makes it better or worse, and how it affects sleep, mood, or daily activities. Bring this diary to each visit so your clinician can see patterns over time.
  • Why is a complete medication and supplement list important?
    Some symptoms are caused or worsened by side effects, interactions, or dosing problems. List every prescription, over the counter medicine, vitamin, and herbal product you use, including doses and how often you take them. Note when a new symptom started in relation to starting or changing a medicine.
  • What personal and family history should I share?
    Include your past conditions, surgeries, allergies, and any exposures at work or home, such as chemicals, dusts, or repetitive strain. A family history of heart disease, stroke, diabetes, cancers, autoimmune conditions, or other major diagnoses, along with ages at diagnosis when you know them, can guide testing and referrals.
  • What will my clinician usually do at the first visit?
    Your clinician will take a detailed history and do a head to toe physical exam. They will ask about when symptoms began, how severe they are, what triggers them, sleep and mood, infections, travel, and how symptoms affect daily life. This information helps focus the workup and avoid unnecessary tests.
  • Which initial tests are commonly ordered?
    Depending on your symptoms, your clinician may order blood tests such as a complete blood count, metabolic panel, thyroid tests, or A1C for diabetes screening, along with a urinalysis. An electrocardiogram may be done if heart issues are suspected. Stool tests or other labs may be added based on your story and exam.
  • How are test results used to reach a diagnosis?
    Results are always interpreted together with your symptom history and physical exam. One abnormal number rarely explains everything. Sometimes tests are repeated or a different method is used to confirm a finding. The goal is to rule in or rule out likely causes in a stepwise way.
  • When are imaging tests or other specialized studies needed?
    Imaging such as X ray, ultrasound, CT, or MRI is ordered when it is likely to change care. Some conditions may also need nerve tests, sleep studies, or endoscopy. Your team should explain why a test is recommended, what it can and cannot show, and what the next steps will be after the results.
  • What symptoms mean I should call emergency services right away?
    Call 911 if you have signs of stroke such as sudden weakness or numbness on one side, sudden trouble speaking, understanding, seeing, or walking, or a sudden severe headache with no known cause. Call 911 for signs of a heart attack such as chest pressure or pain that may spread to the arm, back, neck, or jaw, shortness of breath, cold sweat, nausea, or lightheadedness. Do not drive yourself.
  • When is it helpful to see a specialist or get a second opinion?
    If your condition is complex, rare, or not improving, your primary clinician may refer you to a specialist such as a cardiologist, neurologist, endocrinologist, or gastroenterologist. A second opinion can confirm a diagnosis, suggest additional options, or change the plan. Ask your current clinician to share records and images so the visit is efficient.
  • When should I consider genetic counseling?
    Consider genetic counseling if a condition runs in your family, if you or your child has features that suggest a genetic condition, or if you are planning a pregnancy and want to understand inherited risks. Genetic counselors can review family history, explain testing choices, and help you make informed decisions.
  • What are some common causes of fatigue that my clinician might look for?
    Fatigue can be linked to anemia, thyroid disease, sleep disorders like sleep apnea, infections, mood disorders such as depression, medication side effects, or chronic medical conditions. Clues include heavy menstrual bleeding, snoring, witnessed pauses in breathing, weight changes, sensitivity to heat or cold, low mood, or recent medication changes.
  • What might cause numbness or tingling, and how is it evaluated?
    Numbness and tingling can arise from diabetes, vitamin deficiencies, nerve compression, autoimmune disease, or medicine effects. Your clinician may check blood sugar, vitamin B12 and related labs, and perform a neurologic exam. Nerve studies may be ordered in some cases. Sudden weakness, severe back pain with bowel or bladder changes, or rapidly spreading numbness require urgent care.
  • How are sleep problems such as snoring and daytime sleepiness evaluated?
    Loud snoring, pauses in breathing during sleep, and daytime sleepiness can suggest sleep apnea. Diagnosis usually involves a sleep study at home or in a sleep lab. Treating sleep apnea can improve blood pressure, mood, and energy, and reduce heart and brain risks.
  • How can caregivers help during the diagnostic process?
    Caregivers can help by bringing a short list of top questions, sharing observations the patient might not notice, taking notes during visits, and asking for a clear summary of the plan before leaving. If instructions are confusing, caregivers can ask for plain language explanations and written steps.
  • What can I do before, during, and after visits to support a safe diagnosis?
    Before the visit, gather your symptom diary, medication list, and family history. During the visit, ask what the most likely causes are, which conditions are being ruled out, which test is first and why, and when to follow up. After the visit, review results in your portal, ask about any unexpected findings, confirm how you will be contacted, and know what to do if symptoms change.
  • What should I do if I suspect a serious side effect from a medicine or device?
    Contact your clinician promptly if you think a medicine or device is causing a serious problem. Your clinician can adjust your treatment and may report the event to safety monitoring systems. You can also ask your pharmacist to help you understand possible side effects and interactions.
