For example, if it was caused by liver and gallbladder diseases, long-term treatment may lead to further damage to liver function, affecting bile metabolism, detoxification and other functions; If it was caused by diabetes, long-term high blood sugar status would damage the blood vessels, nerves and other tissues and organs of the whole body, leading to various complications such as cardiovascular and cardiovascular diseases, kidney diseases, retina diseases, etc. The long-term existence of digestive diseases would also affect the absorption of nutrients, leading to malnutrition and other problems.

How does a novel give people a real feeling?

The realism of a novel could be achieved in the following ways: 1. ** Description of details **: For realistic novels, paying attention to details in the description of characters, plots, scenes, etc. can enhance the overall authenticity. For example, the French critical realist writer Balzac is good at this. 2. ** Reflects the Essence **: Even if the plot is absurd, works that can penetrate the appearance of things and reach the essence will also give people a sense of reality, such as the Latin-American magical realism novels such as One Hundred Years of Solitude. 3. ** Character creation is in line with human nature **: In the end, novels are about people. Works that can deeply reveal the truth of human nature can reach a higher level of authenticity. 4. ** Self-consistent internal logic of the story **: The events in the novel conform to the rules set by the author in advance. Different types of novels (such as urban, science fiction, fantasy, etc.) have reasonable plots under their own rules. 5. ** Source of Material: The author's creative materials mainly come from imagination, life experience, and reading.

Too often cited writing technique

Tai Chang Yin's writing style had the following characteristics: 1. In terms of rhyme, the first four sentences had four levels of rhyme, the second five sentences had three levels of rhyme, and the first and second sentences had three levels of rhyme. 2. ** Rhetoric Usage **: Often uses metaphor and other rhetorical devices. For example, in Xin Qiji's "Tai Chang Yin·Jiankang Mid-Autumn Night Fu for Lv Shuqian," the golden wheel was compared to the round moon, and the polished flying mirror was used to describe the new moon. 3. ** Imagination and Association **: Use imagination and association to build a surreal artistic realm. For example, in the poem, he thought of raising a glass to invite Chang'e, asking her for help on how to deal with the bullying of white hair, and also thinking of riding the wind straight into the sky, looking down at the beautiful rivers and mountains, flying to the moon palace, cutting down the swaying osmanthus trees, etc. Through ancient myths and legends, it formed a surreal artistic realm to express the author's emotions and aspirations. For example, when the author's idea of resisting Jin and opposing compromise and surrender was not adopted, and he was not put in an important position, he used words to imagine and express his resentment over the passage of time and the difficulty of achieving success, as well as his political ideals of opposing compromise and surrender and determined to recover the lost land of the Central Plains.
