By the time you have omitted all of those foods and beverages from your diet you are probably wondering if there is anything which you can eat when suffering from gallstones. Actually, they say it is safe to eat pasta, potatoes, cereals and some types of bread, but again, you would need to be careful because some grains are harmful. Other foods which don't seem to cause a problem would include sweet potatoes, tomatoes, cold water fish, berries, garlic, okra, avocados, grapes, pears, papaya and omega-3 oils. In fact, omega-3 oils are actually very good for you and can reduce the risk of heart attack and stroke while also breaking down cholesterol so that it isn't as likely to form gallstones. The best way to understand foods you shouldn't eat with gallstones is to simply learn how to eat a healthy diet which you should be doing in the first place. Even then, once your gallstone problem has been corrected some of the above foods are safe to eat in moderation.
As he mentioned towards the end of his passage, one of the differences he states is, “1. Signs are what a doctor sees, symptoms are what a patient experiences.” if i might add that when he means what a doctor “sees” also means what is smelt, felt, tasted(in rare cases of diagnosis), hear, and sees or the 5 senses. This is the difference that he is talking about when differentiating between a sign and a symptom. A simpler way to word this is that it is all observed by perspective. A fever can be felt and seen by a doctor making it a sign but it can also be a symptom do to the fact that the patient also experiences the fever. So you are right, but technically it is not a special case because there are also other symptoms/signs that fall under this category.
