Heartburn can be caused by acid reflux or gastroesophageal reflux disease (GERD).
STOMACH ULCERS
A CASE TODAY
Stomach ulcers are sores in the lining of the stomach or small intestine. They occur when the protective mucus that lines the stomach becomes ineffective.
Symptoms
The classic symptom of a stomach ulcer is indigestion, also called dyspepsia.
Heartburn can be caused by acid reflux or gastroesophageal reflux disease (GERD).
It is worth noting that not all stomach ulcers cause indigestion.
Stomach ulcer symptoms tend to be more distinct than heartburn, but symptoms can still be vague.
weight loss
nausea and vomiting
not eating because of pain
burping
bloating
pain may be relieved by eating, drinking, or taking antacids
Diet
Dietary changes can help prevent stomach ulcers from developing.
People at risk of stomach ulcers should include more of the following nutrients in their diet:
Fiber: Diets high in soluble dietary fiber reduce the risk of developing stomach ulcers.
Selenium: This may reduce the risk of infection complications and may also promote healing.
Avoiding alcohol and caffeine can also help reduce the risk, as they both cause the body to produce more gastric acid. This can lead to stomach ulcers.
Causes
The two main causes of ulcers of the stomach and small intestine are:
a class of painkillers called nonsteroidal anti-inflammatory drugs (NSAIDs)
Less common causes of stomach ulcers include:
Zollinger-Ellison syndrome: This is a rare disease that causes an excess of stomach acid to be produced.
Certain behaviors and factors increase the chances of developing a stomach ulcer.
These include:
smoking
overproducing calcium, or hypercalcemia
genetics
consuming alcohol frequently
Stomach ulcers are more common in individuals over 50 years of age. People can develop a stomach ulcer at any age, but they are much less common in children.
NSAID drugs and stomach ulcers
A group of painkillers known as NSAIDs carries a risk of stomach ulcers. The two best-known NSAIDs are aspirin and ibuprofen.
Stronger NSAIDs, such as those that need a prescription, are riskier for stomach ulcers than those that can be bought over-the-counter (OTC).
Types
Stomach ulcers are one type of peptic ulcers.
Treatment
If the doctor thinks there is a stomach ulcer, they may try to remove the cause by:
trying the "test-and-treat" approach if the cause is thought to be H. pylori bacteria
H2-receptor antagonists, which prevent the stomach from producing excess acid
antacids or alginate. These are available to purchase over-the-counter.
Symptoms often subside quickly following treatment. However, the treatment should be continued, especially if the ulcer is due to an H. pylori infection.
Surgical treatments
In certain cases, surgery may be an option. For instance, if the ulcer continues to return, will not heal, bleeds, or prevents food from leaving the belly
removing the ulcer
tying off bleeding blood vessels
sewing tissue from another site onto the ulcer
cutting the nerve that controls stomach acid production
Complications from stomach ulcers such as bleeding or perforation are rare.
Diagnosis
Doctors follow the symptoms of a stomach ulcer by asking questions about how the pain feels, where and when it happens, and how frequent and long-lasting it has been.
Endoscopy: A camera is inserted at the end of a long, thin, flexible tube to look at the gut lining. A biopsy may also be taken.
When to see a doctor
Anyone who thinks they may have an ulcer in their stomach should consult their doctor. Any stomach symptoms that last for more than a few days or keep happening need evaluation
A slow-bleeding ulcer can be signaled by symptoms of anemia, such as being tired and breathless. More serious bleeding is an urgent medical problem and can be signaled if blood is vomited up, or stools are black and sticky.

Why do B12 and folate deficiencies lead to HUGE red blood cells?
And, if the issue is DNA synthesis, why are red blood cells (which don't have DNA) the key cell line affected?
For answers, we'll have to go back a few billion years.

RNA came first. Then, ~3-4 billion years ago, DNA emerged.
Among their differences:
🔹RNA contains uracil
🔹DNA contains thymine
But why does DNA contains thymine (T) instead of uracil (U)?
https://t.co/XlxT6cLLXg
3/
🔑Cytosine (C) can undergo spontaneous deamination to uracil (U).
In the RNA world, this meant that U could appear intensionally or unintentionally. This is clearly problematic. How can you repair RNA when you can't tell if something is an error?
https://t.co/bIZGviHBUc
4/
DNA's use of T instead of U means that spontaneous C → U deamination can be corrected without worry that an intentional U is being removed.
DNA requires greater stability than RNA so the transition to a thymine-based structure was beneficial.
https://t.co/bIZGviHBUc

Let's return to megaloblastic anemia secondary to B12 or folate deficiency.
When either is severely deficient deoxythymidine monophosphate (dTMP*) production is hindered. With less dTMP, DNA synthesis is abnormal.
[*Note: thymine is the base in dTMP]

Charting early steps for H₂ infrastructure in Europe.
👉Summary of conclusions of a new study by @AgoraEW @AFRY_global @Ma_Deutsch @gnievchenko (1/17)
https://t.co/YA50FA57Em
The idea behind this study is that future hydrogen demand is highly uncertain and we don’t want to spend tens of billions of euros to repurpose a network which won’t be needed. For instance, hydrogen in ground transport is a hotly debated topic https://t.co/RlnqDYVzpr (2/17)
Similar things can be said about heat. 40% of today’s industrial natural gas use in the EU goes to heat below 100°C and therefore is within range of electric heat pumps – whose performance factors far exceed 100%. (3/17)
Even for higher temperatures, a range of power-to-heat (PtH) options can be more energy-efficient than hydrogen and should be considered first. Available PtH technologies can cover all temperature levels needed in industrial production (e.g. electric arc furnace: 3500°C). (4/17)
In our view, hydrogen use for feedstock and chemical reactions is the only inescapable source of industrial hydrogen demand in Europe that does not lend itself to electrification. Examples include ammonia, steel, and petrochemical industries. (5/17)

Thread on how atheism leads to mental retardation (backed with medical citations🧵💉)
To start with, atheism is an unnatural self-contradicting doctrine.
Medical terminology proves that human beings are naturally pre-disposed to believe in God. Oxford scientists assert that people are "born believers".
https://t.co/kE0Fi588yn
https://t.co/OqyXcGIMJn
It should be known that atheism could never produce an intelligently-functioning society and neither ever will.
Contrastingly, Islam produced several intellectuals & polymaths, was on the forefront of scientific development, boasting 100% literacy
It is also scientifically proven that atheism led to lesser scientific curiosity and scientific frauds, which is also why atheists incline to pseudo-science.
Whereas, religion in general and Islam in particular boosted education.
https://t.co/19Onc84u3g
Atheists are also likely to affected by pervasive mental and developmental disorders like high-functioning autism.
Cognitive Scientists and renowned Neurologists found that more atheism is leads to greater autism.

Science only developed because of Islam, Europe should be grateful to Islam for civilizing their barbaric cult.
