Most hitches employ a removable drawbar, which holds the hitch ball. The bars come in two sizes: 1.25 inches (for lightweight pop-ups and bike racks) and 2 inches (for heavy loads). Hitch balls come in three main flavors: 17/8 inches, 2 inches and 25/16 inches. Generally, the bigger the ball, the more weight it can support. If you own two or more trailers that call for different ball sizes, I recommend buying separate drawbars with the proper balls permanently attached.
Poor blood circulation. Conditions such as cardiomyopathy, heart attack, heart arrhythmia and transient ischemic attack could cause dizziness. And a decrease in blood volume may cause inadequate blood flow to your brain or inner ear.
Heart failure causes reduced blood flow to the rest of your body. If the flow to your brain is lower than usual or your blood pressure is low, you may feel dizzy. Dizziness in people with heart failure is often caused by their medicines. However, irregular heartbeats, which often happen with heart failure, or a temporary drop in blood pressure, caused by rising from a sitting or lying position (postural hypotension), can also cause dizziness. You should discuss any dizziness with your doctor or nurse to identify its cause. Return to Symptoms.
