Introduction
In general, whether implantation of the fertilized egg causes fever depends on individual response. Most people do not typically experience fever during implantation, although a few individuals may have slight fluctuations in body temperature, which do not constitute a typical fever. To better manage physical changes during the implantation period, it is recommended to maintain a regular作息 (routine/schedule), avoid staying up late, and prevent excessive fatigue.
Generally, whether implantation of a fertilized egg will cause fever depends on individual reactions. Most people usually do not experience fever during implantation; however, a few individuals might have minor fluctuations in body temperature, although these are not considered typical fever. The detailed analysis is as follows:
If the implantation process proceeds smoothly and the individual's body is not sensitive to hormonal changes, fever typically does not occur. In such cases, the body may only experience mild implantation bleeding, slight abdominal fullness, or no obvious discomfort. The body temperature remains within the normal physiological range, requiring no special treatment, and normal daily routines can be maintained.
When a few individuals are relatively sensitive to hormonal changes during implantation, they might experience a slight increase in body temperature, usually only 0.3-0.5°C higher than the basal body temperature. This elevation is short-lived and does not meet the medical criteria for fever. It is also not accompanied by symptoms such as headache, fatigue, or muscle aches.
To better manage physical changes during the implantation period, it is recommended to maintain regular作息 (作息 translates as作息 patterns or routines), avoid staying up late and excessive fatigue; maintain a light and balanced diet, and reduce the intake of spicy and stimulating foods.
