Hello,
Your mother's haemoglobin level of 7.6 g/dL indicates significant anaemia, which can explain her weakness, fatigue, and breathlessness.
However, given her history of deep vein thrombosis (DVT), breathlessness also raises concern for a possible pulmonary embolism (blood clot in the lungs), particularly if symptoms are new or worsening.
Possible causes of anaemia include iron deficiency, chronic blood loss, nutritional deficiencies, or underlying medical conditions.
Next Steps
Take her to an emergency department today, particularly because she is breathless and has a history of DVT. Initial assessment should include oxygen saturation, blood pressure, pulse, ECG, and evaluation for pulmonary embolism if clinically suspected. Investigations may include CBC with RBC indices, peripheral smear, reticulocyte count, serum
ferritin, iron studies,
vitamin B12, and folate. Her doctor should evaluate possible sources of blood loss, particularly gastrointestinal or menstrual bleeding, and review any anticoagulant medication. Blood transfusion or intravenous iron may be considered depending on her symptoms, haemodynamic stability, and the underlying cause. Transfusion is not automatically required solely because Hb is 7.6 g/dL.
Health Tips
Until medically assessed, avoid strenuous activities and allow adequate rest. For constipation, adequate fluids and dietary fibre may help, but the underlying cause and any current iron supplements should be reviewed. Seek emergency care immediately if she experiences worsening breathlessness, chest pain, fainting, rapid heartbeat, coughing blood, or severe weakness. My recommendation: Her combination of significant anaemia, breathlessness, and previous DVT warrants prompt hospital assessment. Do not stop prescribed blood thinners without medical advice. Wishing your mother a speedy recovery!
