An English description is being prepared. Japanese description:
内科医は脳神経内科、循環器内科、消化器内科、呼吸器内科等様々な専門分野に分かれておりそれぞれの専門に応じた知識、技術が求められるが、ここでは共通した主な仕事の内容について記述する。
まず、患者から症状などの話を聞く問診を行う。次に、視診、聴診、打診、触診を行って患部の状態を確かめる。必要に応じて、尿検査、血液検査、超音波検査、心電図検査なども行う。結果をカルテに入力し、入手したデータを分析し、総合的に判断して病名を診断する。その上で、治療法や投与する医薬品等を選択し、処方箋を出す。なぜ診察、検査、治療が必要なのか、診断結果や治療法については患者や家族に正確に、丁寧に説明を行う。必要があれば注射、吸入などの措置を行う。慢性疾患、生活習慣病の場合は、投薬のみならず、食生活、適度の運動など患者の生活全般について指導・助言を行う。病気の予防指導を行う場合もある。
病院や診療所などで働く勤務医と医院を営む開業医がおり、仕事は若干異なる。
大きな病院に勤務する勤務医は、特に、消化器や循環器など専門分野が明確に分かれている場合が多く、他の医師などとチームを組み、専門的な治療を行う。担当する入院患者の回診だけでなく、当番制で外来患者の診療も行う。
開業医は、外来での医療（診察や診断後と治療行為）が主な仕事であり、診察と同時に検査や処置もこなす。地域住民の健康診断、近所の学校などの校医、高齢者の自宅に出かけての往診など、地域に密着した医療活動を行う。自分の医院やクリニックで対応が難しい場合は、他の総合病院等に紹介する。

What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (the job-openings-to-applicants ratio), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →

Will AI replace 内科医? AI replacement risk
How AI is changing this job
A written analysis for this occupation is being prepared.
AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
Labor demand for 内科医
A ratio above 1.0 means there are more job openings than applicants (a labor shortage). The 5- and 10-year figures are estimates from the openings ratio, wage momentum and AI replacement risk.
