What a Psychiatrist Is

A psychiatrist is a medical doctor, holding an MD or DO degree, who specializes in the diagnosis and treatment of mental health conditions. Their path to practice requires four years of undergraduate education, four years of medical school, and then a four-year psychiatric residency. Some complete additional fellowship training in subspecialties. Total postgraduate training: eight or more years.

Because they hold a medical degree, psychiatrists can:

• Diagnose mental health conditions using clinical criteria
• Prescribe and manage psychiatric medications
• Order and interpret laboratory tests and medical workups
• Assess whether physical health conditions are driving or worsening psychiatric symptoms
• Monitor how medications interact with the body’s physical systems

Psychiatrists are medical doctors who can prescribe medication and conduct comprehensive medical and psychiatric assessments. The prescription authority and the medical lens are the core of what makes them different from other mental health professionals.

The First Appointment: What Actually Happens

The first psychiatric appointment is an intake evaluation, not a 15-minute check-in. The initial evaluation typically lasts 60 to 90 minutes. It is longer than follow-up visits specifically because the psychiatrist is building a complete clinical picture from scratch.

Your Current Symptoms

The psychiatrist starts by asking about what brought you in. How long have you been experiencing symptoms? Are they getting better or worse? How are they affecting your work, relationships, and daily life? These questions are how the psychiatrist begins to map the clinical terrain.

Medical and Psychiatric History

Past diagnoses, prior hospitalizations, previous medications and how they worked, family history of mental health conditions. This history provides context that shapes the diagnostic picture. A first episode of depression in someone with no family history looks different clinically from a first episode in someone whose parent and sibling both have bipolar disorder.

Medications and Substances

Current prescriptions, supplements, caffeine, alcohol, and substance use. Drug interactions, underlying conditions that certain medications contraindicate, and substance use patterns that can cause or worsen psychiatric symptoms all affect prescribing decisions.

Mental Status Examination

The psychiatrist conducts a mental status examination (MSE) during the first evaluation. This is a clinical assessment of how you appear, think, and behave in the session. It covers mood and affect, thought process, any unusual perceptions, cognition, insight, and judgment. This is not a test that you pass or fail. It is the psychiatrist observing how you present clinically and noting anything that informs diagnosis or safety.

Risk Assessment

The psychiatrist will ask about suicidal ideation, self-harm, and in some circumstances, thoughts of harming others. This can feel uncomfortable, but it is a standard and necessary component of psychiatric evaluation. Asking about these thoughts directly does not increase risk. It opens the conversation that allows a safety plan to be built if one is needed.

End-of-Session Discussion

By the end, your provider will summarize what they’ve learned and discuss next steps, including further assessment, therapy, or medication management. This includes a preliminary diagnosis, treatment options, and a follow-up plan. Some people leave with a prescription; others leave with a therapy referral or a plan to gather more information first.

What a Psychiatrist Can Do That Others Cannot

Beyond prescribing, the medical training of a psychiatrist allows them to catch something that a therapist or psychologist cannot catch: a physical condition presenting as a psychiatric one.

Several common medical conditions can produce symptoms that look exactly like depression or anxiety: hypothyroidism, anemia, vitamin B12 deficiency, adrenal dysfunction, and certain sleep disorders. A psychiatrist can order thyroid panels, metabolic panels, and other baseline labs to rule out these contributors. Without medical training, a clinician working from symptoms alone may miss a treatable physical cause entirely.

When appropriate, the psychiatrist will request permission to contact your primary care provider to coordinate care and ensure safe prescribing and monitoring. Medication safety requires knowing the full picture of your physical health.

Why Most Psychiatrists No Longer Do Ongoing Talk Therapy

Fifty years ago, a psychiatrist might have seen patients for weekly 50-minute psychotherapy sessions. That model has largely disappeared. For a variety of reasons, including the way insurance reimbursements are structured, many psychiatrists primarily see patients for medication assessment and management, which are often 15-minute sessions.

This is not a failure of the system. It is a recognition that different clinicians have different training and different roles. A psychiatrist who sees 30 patients in a day doing 15-minute medication checks can provide medication oversight to far more people than one who spends 50 minutes per patient. The therapy is often better delivered by someone whose training focuses specifically on it.

What Follow-Up Care Involves

Starting a new medication. If you are starting a new psychiatric medication, most psychiatrists schedule a follow-up within 2 to 4 weeks to assess early response and catch any side effects that need adjustment.

Stable medication. Once medication is working and side effects are managed, visits may shift to every one to three months.

Ongoing monitoring. Some medications require lab work. The psychiatrist coordinates and interprets these tests.

The challenge is the gap between appointments. If medication side effects emerge two weeks after a visit and the next appointment is in two months, that is two months during which something correctable goes uncorrected. The best predictor of successful treatment depends on the quality of the therapeutic relationship and the information flow between appointments.

This is why continuity of care matters as much as the appointments themselves. A model that allows a prescriber to see what is happening between visits changes what is possible in treatment outcomes.

When You Should Consider Seeing a Psychiatrist

• You are experiencing significant depression, anxiety, mood instability, or other symptoms interfering with daily functioning
• A therapist or primary care provider has suggested you would benefit from psychiatric evaluation or medication
• You have tried therapy and symptoms remain persistent or severe
• You have a family history of a serious psychiatric condition and want a thorough evaluation
• You have comorbid physical health conditions that may be interacting with psychiatric symptoms
• You need a clinician who can prescribe and monitor psychiatric medication

What Happens When Access Is Constrained

For most people, the hardest part of seeing a psychiatrist is not the appointment itself. It is the wait to get in. Only 18.5% of psychiatrists were available to see new patients in a 2023 national study, with a median wait of 67 days.

For people with depression or anxiety, 67 days without clinical attention is not an acceptable wait. This is the structural reality that has driven the growth of psychiatric nurse practitioners, physician assistants with psychiatric training, and telehealth platforms into the care gap.

“The shortage of psychiatrists creates a specific problem for medication management,” says Shannon Carres, Psych P.A., of the SiggyMD clinical team. “When a patient can’t get in for two months, the decision about whether to start medication, what to start, and how to monitor the first weeks gets pushed out. That delay has clinical consequences. Models that can move faster without sacrificing oversight are what that gap requires.”

What Members Are Saying

Generalized Anxiety Disorder

“I had heard about psychiatrists but never really understood what they did versus a therapist. When I finally went, the first appointment was thorough in a way I didn’t expect. They asked about my whole health history, ordered bloodwork, and actually looked at the full picture of what was going on. That felt different from just talking about my feelings.”

Depression, Treatment Beginning

“I was nervous that the appointment would feel clinical and cold. It wasn’t. The psychiatrist explained what she was looking for, what the medication options were, why one might work better for me than another, and what to watch for in the first few weeks. I left feeling like someone actually had a plan for my care.”

Taking the Next Step

Seeing a psychiatrist is the beginning of a clinical relationship, not a one-time event. The evaluation is how your prescriber builds the clinical picture that makes treatment decisions safe and informed. What happens between appointments, how consistently symptoms are monitored, whether side effects are caught and addressed, shapes long-term outcomes.

If you are ready to start care but concerned about access, SiggyMD offers an anonymous, free intake reviewed by a licensed prescriber, without the 67-day wait. Start your intake at SiggyMD and a licensed clinician will evaluate your full clinical picture and outline what treatment could look like for your specific situation.
