Hemogram: What does hemoglobin 6.8 g/dL mean?

A hemoglobin around 6.8 g/dL can be serious in some cases. Seek immediate emergency care if any of the following occur:

• Chest pain or pressure
• Severe or rapidly worsening shortness of breath
• Fainting, loss of consciousness or sudden severe dizziness
• Major uncontrolled bleeding
• Sudden severe headache or new neurological signs (speech difficulty, weakness on one side)

Many conditions can lead to low hemoglobin. The list below outlines common categories but the exact cause needs individualized assessment.

• Acute or chronic blood loss (for example gastrointestinal bleeding or heavy menstrual bleeding)
• Nutritional deficiencies (iron, vitamin B12, folate)
• Conditions affecting bone marrow production
• Anemia related to chronic disease or inflammation
• Hemolytic processes (red blood cells breaking down faster than normal)

This list is illustrative; a clinician’s evaluation is needed to determine the specific cause.

Specialties commonly involved in evaluating low hemoglobin include the following. If you have emergency symptoms, contact Emergency Medicine first and you may then be referred to another service.

• Hematology — for blood and bone marrow evaluation
• Internal Medicine — to investigate systemic causes
• Family Medicine — for initial assessment and referral

Being prepared can speed up evaluation. Your clinician will take a history, perform a physical exam and may order further tests or imaging. Helpful information to provide includes:

• When symptoms began and how severe they are (fatigue, dizziness, shortness of breath, etc.)
• Any history of bleeding (heavy periods, blood in stool, blood in urine, recent injuries)
• Chronic conditions and regular medications
• Previous blood tests or treatments for anemia

This guidance is general; follow your clinician’s recommendations for specific medical decisions.
