From the Guidelines
For a young female with recent weight gain, fatigue, menorrhagia, infertility, and a family history of hypothyroidism, I strongly recommend conducting a comprehensive subjective assessment focusing on thyroid-related symptoms, as her symptoms and family history suggest a high risk for hypothyroidism, which can significantly impact her morbidity, mortality, and quality of life.
Key Assessment Areas
- Ask about the timing and extent of weight gain, severity and patterns of fatigue, detailed menstrual history including flow amount and duration, and specific fertility challenges, as these symptoms are commonly associated with hypothyroidism 1.
- Inquire about other thyroid symptoms such as cold intolerance, hair loss, dry skin, constipation, and mood changes, which can help identify potential thyroid dysfunction 1.
- Gather information about her diet, particularly iodine intake, exercise habits, stress levels, and sleep patterns, as these factors can influence thyroid function and overall health.
- Ask about medication use, including oral contraceptives or hormone therapy, which may impact thyroid function or interact with thyroid medications.
- Explore her family history beyond her grandmother, looking for other thyroid disorders or autoimmune conditions, as a family history of thyroid disease increases her risk for thyroid dysfunction 1.
Importance of Assessment
This subjective assessment is crucial as it will guide appropriate laboratory testing, typically including TSH, free T4, and possibly thyroid antibodies, to confirm diagnosis and inform treatment decisions, ultimately improving her quality of life and reducing the risk of long-term complications associated with untreated hypothyroidism 1.
Prioritizing Recent and High-Quality Evidence
The most recent and highest quality study, published in 2015 in the Annals of Internal Medicine 1, emphasizes the importance of assessing risk factors for thyroid dysfunction, including female sex, family history of thyroid disease, and symptoms such as weight gain and fatigue, highlighting the need for a comprehensive subjective assessment in this patient.

From the Research
Subjective Assessment for Young Female with Recent Weight Gain, Fatigue, Menorrhagia, Infertility, and Family History of Hypothyroidism
The patient's symptoms, including fatigue, weight gain, menorrhagia, and infertility, are consistent with hypothyroidism, a disease in which the thyroid gland does not produce enough thyroid hormone 2. Given her family history of hypothyroidism, particularly her grandmother's history of the condition, it is essential to consider the possibility of hypothyroidism in this patient.
Key Symptoms and Risk Factors
- Fatigue, weight gain, and menstrual abnormalities are common symptoms of hypothyroidism 2, 3, 4
- Infertility is also a symptom of hypothyroidism, which can affect reproductive health 2, 3
- Family history of hypothyroidism increases the risk of developing the condition 2
- The patient's symptoms and family history suggest a potential diagnosis of hypothyroidism, which requires further evaluation and testing
Diagnostic Evaluation
- Thyroid-stimulating hormone (TSH) levels can be used to evaluate thyroid disorders and diagnose hypothyroidism 2, 3, 4
- Free thyroxine (FT4) levels can also be measured to confirm the diagnosis of hypothyroidism 4
- The American Thyroid Association recommends initial screening for thyroid disease at age 35 years and every 5 years thereafter 2
