Obesity in the United States is increasing, with the most recent national data indicating a prevalence of 41.9%. Obesity is generally considered a body mass index (BMI) of 30 kg per m2 or greater; however, increased waist circumference (female: 35 inches or greater; male: 40 inches or greater) may be a more accurate indicator of obesity, particularly in older adults. For patients who are overweight or obese, the history should include whether patients are taking medications that can increase weight and identifying comorbid conditions contributing to or resulting from obesity. ⋯ Pharmacotherapy with anti-obesity medications such as glucagon-like peptide-1 receptor agonists, sympathomimetics, and others should be considered for any patient with a BMI of 30 kg per m2 or greater and for any patients who are overweight (i.e., BMI of 27 kg per m2 or greater) with metabolic comorbidities. Referral for bariatric surgery should be considered for patients who meet the criteria. Successful management requires individualized support systems with periodic follow-ups through each phase of treatment.

Pulmonary hypertension includes a diverse set of conditions defined by a mean pulmonary artery pressure greater than 20 mm Hg found during right heart catheterization that can lead to right-sided heart failure and death if untreated. The most common cause of pulmonary hypertension is left-sided heart failure, followed by chronic obstructive lung disease. Pulmonary hypertension presents as unexplained dyspnea on exertion and possible findings of right-sided heart failure. ⋯ Patients with pulmonary hypertension have a high risk of perioperative complications, and detailed specialty preoperative evaluation is recommended. Physicians should counsel patients of childbearing age with pulmonary hypertension to prevent pregnancy to avoid worsening the severity of pulmonary hypertension and fetal loss. Pulmonary hypertension is severe, chronic, progressive, and challenging to treat; therefore, family physicians should update the patient's immunization status, screen for and address mental health conditions, and discuss goals of care and advance directives with patients.

Conjunctivitis caused by viruses, bacteria, or allergies is one of the most common eye conditions in primary care. There is no single sign or symptom that accurately differentiates viral from bacterial conjunctivitis. A comprehensive history and physical examination can guide diagnosis. ⋯ Bacterial conjunctivitis is more common in children and typically presents as mucopurulent discharge with the eyelids matted shut. Delayed antibiotic prescribing has been found to have similar symptom control as immediate prescribing. Ophthalmology referral is indicated for conjunctivitis in a neonate or patients with severe pain, decreased vision, recent ocular surgery, vesicular rash on the eyelids or nose, history of rheumatologic disease, or immunocompromised state.
