Have chronic gastritis, constipation, palpitation and unrefreshing sleep. What could be the solution?

Stress, reflux. These symptoms could be due to stress, anxiety, and possibly reflux. Without a full physical, you also need to consider a cardiac issue and a GI issue. Consider and evaluation by a cardiologist, gastoenterologist and your family physician.

I have chronic gastritis, constipation, palpitation and unrefreshing sleep. Any solutions?

Magnesium for stress. Your body is obviously under a lot of stress (emotional and/or physical). I strongly recommend supplementing with magnesium (particularly effective is peter gillham's natural vitality calm), which helps specifically with musculoskeletal tension, constipation, cardiac arrhythmias & palpitations, insomnia, and anxiety. Consider digestive enzymes and probiotics to aid digestion & melatonin for sleep.

What was introduced at about the time you developed your symptoms? Some of the symptoms - maybe all can be caused by anxiety so cognitive-behavior therapy, biofeedback, or anti-anxiety medicines (buspirone) may be indicated. Nonrestorative sleep can be apnea, rls, meds, depress.
