Recovery guide Timeline
Heart surgery recovery stages
Recovery is not one long slope. It comes in phases with different jobs, and knowing which phase you are in tells you whether a flat day is a problem or simply Tuesday.

Stage 1 — hospital, days one to five
Drains and lines come out, you sit, then stand, then walk. Breathing exercises start immediately and chest support is fitted. Pain is at its highest here, and pain relief is prescribed to let you move and breathe rather than simply to feel comfortable.
Stage 2 — the first fortnight home
The quietest and often hardest phase. Fatigue dominates, sleep is broken, appetite is poor, and sternal precautions are in full force. The work of this stage is small and repeated: short walks several times a day, the breathing routine, and protecting the chest when you cough or move.
Stage 3 — weeks three to six, rehabilitation
Cardiac rehabilitation begins and progress becomes visible: distance builds, confidence returns, and the flat days get further apart. The bone is knitting but is not yet strong, so lifting limits still apply even when you feel able.
Stage 4 — six to eight weeks and beyond
At the surgical review the sternum is usually judged healed, support is discontinued and restrictions are relaxed. Driving and work are discussed. Energy is the last thing to return — three to six months to feel genuinely yourself is common, and it is not a sign anything has gone wrong.
Timelines shift with your procedure, your health beforehand and any complications. Your team’s version is the one that counts.
Questions patients ask
+What are the stages of recovery after open-heart surgery?
Broadly four: hospital care over the first days, a quiet fortnight at home dominated by fatigue, cardiac rehabilitation through weeks three to six, and the six-to-eight-week review at which the sternum has usually healed and restrictions are relaxed.
+Is it normal to go backwards some days?
Yes. A strong day followed by a flat one is the usual pattern rather than a setback. Compare yourself with last week rather than with how you felt before surgery.
+When is the sternum considered healed?
Usually at six to eight weeks, confirmed at your surgical review. That is when lifting limits and chest support are typically reviewed.
