What to expect your first week of treatment

The unknown is part of what makes starting treatment scary. Knowing roughly what the first week looks like takes some of the fear out of it. While every program differs, the shape of the first week in residential or PHP care is fairly predictable, and the structure that can feel overwhelming at first is the same structure that helps recovery take hold.

This guide walks through what to expect, the feelings that are normal, and what helps.

The first day: intake and orientation

The first day is mostly logistics and getting oriented, not intensive therapy. Expect a medical check (vital signs, labs, a physical review), a clinical assessment, and paperwork.¹ Many programs also include a psychiatric evaluation in the first few days to assess co-occurring conditions and review any medication. If the eating disorder has caused medical instability, the early focus is on medical stabilization before the full treatment routine begins. You will tour the space, meet staff and other participants, and begin building an initial treatment plan and meal plan with the team. It is normal to feel nervous, numb, or relieved, sometimes all at once.

Meals and the daily routine

Supported meals are central from early on. Meals are eaten with staff and often as a group, with help managing the anxiety that eating can bring. A dietitian builds the meal plan, working with genuine medical, religious, or ethical dietary needs while helping separate those from restrictions driven by the eating disorder. The structure is meant to be supportive, not punitive.² The rest of the day fills with individual therapy, group therapy, dietitian and medical check-ins, skills groups, and structured downtime. The predictability is intentional: fewer food and routine decisions leaves more room to focus on recovery.

Feelings that are normal

The first few days are often the hardest. Regular eating after a period of restriction or chaos is physically and emotionally demanding, and a new environment adds to that. Nutritional rehabilitation is a core part of eating disorder treatment, and the early adjustment is expected.³

Practical questions to ask before arrival

Policies vary, so a quick call ahead helps you prepare:

• What should I bring, and what is not allowed?
• What is the phone and device policy, especially early on?
• How are meals and dietary needs handled, including allergies or patterns like vegetarian or vegan?
• Can schoolwork continue, and is academic support available?
• How and when is family involved or able to visit?
• What does a typical day look like?

What to bring (and what to leave)

Programs send a packing list, so follow theirs first, but in general:

• Bring comfortable clothes for several days, any prescribed medications in their original bottles, a list of current providers and emergency contacts, insurance information, and a few personal comfort items (a book, photos, a journal).
• Leave or expect limits on items that can interfere with treatment: many programs restrict or hold phones and devices early on, and most do not allow outside food, supplements, exercise equipment, or anything that could be used for self-harm. Mirrors and scales are often managed by staff.

Knowing this ahead of time prevents an anxious first day spent surrendering items you did not expect to.

How it differs for teens and adults

For adolescents, family is central from the start. Parents are usually involved in the meal plan and family therapy, sometimes within the first days, because family-based approaches put parents in charge of early refeeding.⁴ Keeping up with school is part of the plan too; many programs make room for academics so a teen does not fall behind during treatment. Expect more contact and a bigger family role.

For adults, treatment is more self-directed, with family involved according to the person's wishes and the program's model. The first week still centers on stabilizing eating and settling into structure, but the autonomy and the contact policies usually differ.

For families

If your loved one is starting treatment, the first week can be hard for you too, especially with limited contact in some programs. Trust the process, take part in any family programming offered, and use the time to look after yourself.⁵ Our guide on helping a loved one start treatment covers supporting someone through care.
