Your concerns run deep. Yes, the exact causation of your reflux and acid indigestion is important to determine. Daily regular acid reflux is very unusual in a young person. Gastroenterology Consultation with special tests is warranted. Possible causes are: 1 - gastric emptying slow down due to chronic inflammation from chronic high acid secretion; 2 - peptic ulceration and peptic gastritis; 3 -chronic infection such as Helicobacter Pylori infection in the stomach; 4 - duodenal inflammation with swelling and ulcer formation; 5 - gastrin hormone overproduction; So, evaluation is warranted and needed: ultrasound, gastric emptying studies, blood tests. Meanwhile, Recommendations: -eat small portions of food; chew thoroughly; minimize sweet foods; minimize processed carbohydrates; consume fresh fruits and vegetables daily; chew thoroughly and eat slowly and do not eat too much at once; avoid coffee; avoid alcohol; exercise after eating by

How many times do you get an ultrasound test during pregnancy?

Several factors affect survival with a heart transplant. Factors include underlying vascular disease, presence of diabetes or not, level of kidney function, age of the person getting a transplant, plus donor variables too: including age, time between removal and implant, other illnesses in the donor. On average, survival is over 70% after one year of receiving a heart transplant; clinical care must be tight with frequent follow-up visits and blood tests and heart function evaluations; medication matters as well.

Drug overdose?

It is a wise and appropriate concern. The prescribing physician must be involved with her overuse. Overuse is dangerous.

Can you exercise with a hernia?

Yes, you are able, but with special cautions and special considerations and special choices. The important decision is which exercises are safe for you with a hiatal hernia and which are potential risks. The hiatal hernia exists in your diaphragm where your esophagus joins your stomach. The hernia bulges there up into your chest. So, exercises which tense abdominal muscles and increase intra-abdominal pressures will push the stomach tissue through the diaphragm hernia up into your chest. Sit ups: no. Push ups: no. Weight training using large muscles of chest, back, shoulders, and thighs: no. One arm curls: yes. One arm tricep extensions: yes. Walking: yes. Running: no. Riding bike: with apparatus: yes; free bike riding with curled handlebars: no. Be care and be wary; you will sense when abdominal wall muscles are tightening, then stop and ease off.

Gastric ulcers are serious and of great concern. Gastric ulcer only develops when there is breakdown of the inner stomach protective barrier. The stomach must have a completely intact barrier that protects against the strong gastric acid that is secreted within the stomach and is able to burn cell membranes and cellular connections. Mucus is a component of the protective barrier. Any disruption will lead to erosion and ulceration, which denotes burning by the acids and corrosion. Ulcers may be shallow and superficial. Ulcers may be deep and penetrating. Ulcers may erode blood vessels with bleeding. Ulcers may penetrate very deep through the stomach wall. Prevention is essential. Ulcers can evolve from aspirin, from other NSAID MEDICATIONS, from alcohol, from local infection of bacteria like Helicobacter pylori, or from other etiologies such as cancer. Discovering root basic causation is essential for basic corrective action. Preventive habits are essential. Avoiding compounding habits too is essential, like avoiding alcohol and aspirin and or NSAID MEDICATIONS together. Dietary habits that do not promote high acid secretion are important: strong spices, large meat intakes, overeating all stimulate acid secretions. And ulcers reoccur. So, be informed and take care to get help.

Food poisoning?

Happy to explain. Yes, your observation is accurate. You did consume tainted food. The green change to stool passage is evidence of mild colitis with inflammatory mucus secretion. READ MORE
Happy to explain. Yes, your observation is accurate. You did consume tainted food. The green change to stool passage is evidence of mild colitis with inflammatory mucus secretion. Steps to take: if no fever or blood, an antibiotic is not essential; if symptoms worsen, then two days of antibiotics is helpful to resolve; at this moment in time, obtain probiotics and take right away. Florastor is optimal. Take two to three doses today and adjust diet today to bananas, whole grains, apples, and toast only for two days. No milk or dairy or animal fat. And take Pepto Bismol one ounce immediately and then one ounce at three-hour intervals while awake, for two days.

Yes, the guideline and practice of isolation with contagious infections is important and effective. Essentials are: not touching; not sleeping together; not eating at the same table; keeping six feet apart; separate beds and bedrooms; bathroom use spaced by several minutes with complete wipe over countertops, sinks, toilet, and separate towels; daily laundry of clothes and pillowcases and sheets and towels; paper towels for routine hand washing; mask if car riding; ideally separate sitting rooms. It is definitely a helpful practice too to clean face and lips and nostrils two to three times each day. Discard q-tips after cleaning. Clean hands. A q-tip wetted with hydrogen peroxide is very effective at cleaning and disinfecting nostrils. Do this three times each day also.

How bad is 46 HDL for a woman?

Hello,

The HDL of 46 is low and this permits atherosclerosis to evolve in mid-life years. HDL is a carrier of cholesterol from plasma and from blood vessel walls back into the liver where it is metabolized. Thus, HDL serves in a positive protective way. You have an opportunity to make it better. Your new chapter of living with smoking cessation and exercise and diet change
and aiming for weight reduction are all proven to benefit HDL plasma levels; your HDL will rise over time and the increased number of HDL carriers will scavenge bad cholesterol and move bad cholesterol back to the liver for metabolism. Diet is very important: more vegetarian foods: foods of color: reds, greens, purples, blues, orange make a positive difference; eliminating saturated animal fats also make a huge positive difference: eating very lean animal protein is healthy; fish oil and vegetable oils are healthy; fish oil can make a positive difference to HDL; omega-3 in particular; olive oil is beneficial; cumin oil is beneficial; astaxanthin is beneficial; and data are showing that vitamin K2 makes a huge beneficial impact on atherosclerosis; this can be added in capsule form.
