Hello, yes, no harm. Patients with hyperlipidemia can donate blood, please feel free to donate blood. The reason why people get fat is usually because of the imbalance between food absorption and consumption. Individual comrades donate blood to make up after rest, and the energy intake greatly exceeds the energy consumption, which contributes to the body getting fat. According to the current average living standard, you just need to adjust your diet a little. If you are not afraid of being fat, make it up! At the same time thank you for your love. At present, the blood source is really nervous!
