The aim of this study is to look at how the study medicine behaves in the participant's body and how it is removed from the participant's body. The study compares Japanese and Caucasian people who are normal weight, overweight or with obesity. The participants will either get NNC0174-0833 (a potential new medicine) or placebo (a "dummy" medicine similar to the study medicine but without active ingredients) - which treatment any participant gets is decided by chance. Participants will get 1 injection by a study nurse at the clinic. The injection will be with a needle in a skin fold in the participant's stomach area. The study will last for about 4 months, but duration of participation for any participant will last up to about 2 months. The participants will have 8 clinic visits with the study staff.
