Ive Been having a lot of health issues for a year I feel full with no food or very little. I have burning in my stomach most of the time. I have dizziness when I stand. I am extremely tired all the time. I have nausea and sickness everyday. I’ve lost a lot of weight. My symptoms are every day. I tried lanzoprozol for excess acid but they did not help. The doctors don’t know what it is. I don’t know if it’s my acid levels. I had my gall bladder removed several years ago. Im 26 years old female. Any suggestions welcome thank you.
Pulmonary function tests (PFTs) are often done after lung cancer is diagnosed to see how well your lungs are working (for example, how much emphysema or chronic bronchitis is present). This is especially important if surgery might be an option in treating the cancer. Surgery to remove lung cancer may mean removing part or all of a lung, so it’s important to know how well the lungs are working beforehand. Some people with poor lung function (like those with lung damage from smoking) don’t have enough lung reserve to withstand removing even part of a lung. These tests can give the surgeon an idea of whether surgery is a good option, and if so, how much lung can safely be removed.
The modern era of testing general relativity was ushered in largely at the impetus of Dicke and Schiff who laid out a framework for testing general relativity.    They emphasized the importance not only of the classical tests, but of null experiments, testing for effects which in principle could occur in a theory of gravitation, but do not occur in general relativity. Other important theoretical developments included the inception of alternative theories to general relativity , in particular, scalar-tensor theories such as the Brans–Dicke theory ;  the parameterized post-Newtonian formalism in which deviations from general relativity can be quantified; and the framework of the equivalence principle .
