Why am I still depressed despite Sertraline?

Question

Hello doctor,

I am a 46-year-old man diagnosed with major depressive disorder for the past seven years. My recent PHQ-9 score is 18, which my psychiatrist said indicates moderately severe depression. I am currently on Sertraline 100 mg daily, but my mood remains low, I feel fatigued most of the day, and I have lost interest in activities I used to enjoy.

I have had type 2 diabetes for 10 years, with my latest HbA1c at 8.3 percent and fasting blood sugar at 182 mg/dL, despite being on metformin and insulin. My blood pressure averages 148/94 mmHg, and I have dyslipidemia with LDL 160 mg/dL and triglycerides 230 mg/dL. I often sleep poorly, averaging four to five hours a night, and wake up unrefreshed. My BMI is 31.2 kg/m², and I feel constantly tired.

Because of poor motivation, I miss my exercise routine and sometimes skip medications. My doctor mentioned newer options like Bupropion or Esketamine nasal spray, but I am concerned about safety with my diabetes and high blood pressure.

I want to know what the best treatment plan is for my depression, along with diabetes, hypertension, and cholesterol problems, and whether therapy or lifestyle changes could help improve both my mood and physical health.

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I have read your query and can understand your concern.

Your situation shows how depression, diabetes, high blood pressure, and abnormal cholesterol can feed into each other. Low mood reduces energy and motivation, which makes it harder to manage diet, exercise, and medications. Poor metabolic control, in turn, can worsen fatigue and mood symptoms.

A PHQ-9 (patient health questionnaire-9) score in the moderately severe range suggests your depression is not adequately controlled. If Sertraline has not been enough, your doctor may consider adjusting the dose, switching medications, or adding another antidepressant.

Bupropion is sometimes used in this setting. It may improve energy, focus, and motivation, and it is generally weight-neutral or linked to modest weight loss, which can support diabetes care. However, it can increase blood pressure in some people, so monitoring would be important given your hypertension.

Esketamine nasal spray is reserved for treatment-resistant depression. It can work quickly for some patients, but it may raise blood pressure and must be given in a certified clinic with close monitoring.

Medication alone is rarely the full solution. Cognitive behavioral therapy can help reshape negative thought patterns, improve coping skills, and strengthen adherence to diabetes and blood pressure treatment.

Lifestyle changes also matter, but they must be realistic. Small, structured steps such as short daily walks, consistent sleep timing, and gradual dietary adjustments are more sustainable than drastic plans.

A coordinated plan involving your psychiatrist, endocrinologist, and primary care physician is essential. The goal is to treat depression effectively while protecting cardiovascular and metabolic health. Better control of blood sugar, blood pressure, and cholesterol can itself improve energy and mood over time.

I hope this answers your query.
