Diabetes is a disease of metabolism, appears due to either the pancreas not producing enough insulin or the cells of the body not responding properly to the insulin produced.

Let's understand some technical terms related to this disease.

Carbohydrates (food)
Carbohydrates are one of the three main energy sources for the body (the others are fat and protein). Human body breaks down carbohydrates to get glucose, which then provides energy to the body.

Glucose (food)
A simple sugar found in the blood; it is the body's main source of energy. In order to use it properly, the body should have a sufficient level of the insulin hormone.

Glycogen (a form of fat)
When glucose in the blood is high, with the help of insulin hormone, this excess glucose normally is stored as 'glycogen' within various muscle cells and liver cells. This process preserves water along with glycogen.

Metabolism (bio-chemical process)
The bio-chemical process that occurs within body cells, that converts food along with oxygen into energy in order to maintain life. Insulin helps the process of metabolism. If body cells develop insulin resistance, then, body cannot use glucose (food), and, much percentage of glucose (in blood) will be converted to fat.

Pancreas (a gland)
Pancreas produces Insulin and glucagon hormones. Insulin gives signals to the cells of the muscles, fats, tissues, etc to take glucose inside the body cell from the blood to get life energy/fuel.

Insulin hormone
Insulin is a hormone that helps the body use glucose. Insulin allows glucose to enter the body cells that need it. Without insulin, glucose can’t get to where it needs to go. People with type 1 diabetes don’t have this hormone; people with type 2 diabetes either don’t have it or their bodies (cells) aren’t able to use it.
If the insulin itself is defective, then glucose will not be absorbed properly by the body cells that require it, and it will not be stored appropriately in the liver and muscles. The net effect is persistently high levels of glucose in the blood.

Glucagon hormone
Glucagon is made by the pancreas. It raises the blood glucose level, so it counteracts the effects of the insulin hormone. If someone with diabetes has very low blood glucose (hypoglycemia), then a glucagon injection may help raise the blood glucose level.

Diabetes Type 1
A type of diabetes in which the insulin-producing cells (called beta cells) of the pancreas are damaged. When beta cells are damaged, the pancreas cannot produce sufficient insulin for metabolism tasks in the body. Body with type 1 diabetes produce little or no insulin, so glucose cannot get into the body's cells for use as energy. This causes blood sugar to rise. People with type 1 diabetes must use insulin injections to control their blood sugar. So, Type 1 is an insulin deficiency/insufficiency disease. One reason for this disease is autoimmune system attack on insulin-producing cells in pancreas gland.

Diabetes Type 2 (Hyperglycemia)
A type of diabetes in which the insulin produced is either not enough or the body cells does not respond normally to the insulin amount present; therefore, glucose in the blood cannot get into the body's cells for use as energy. So, Type 2 is an insulin resistance disease. This is the most common type of diabetes. Type 2 is primarily due to abnormal lifestyle factors and/or genetical disorders.

In both cases, body cells do not receive glucose (food), and this causes problems in the entire body.

Diabetic ketoacidosis (DKA). If body can't get enough glucose for fuel, it breaks down fat cells instead. This creates chemicals called ketones. Liver releases the sugar it stores to help out. But, again, body can’t use it without insulin, so sugar builds up in the blood, along with the acidic ketones. This combination of extra glucose, dehydration, and acid buildup is known as "ketoacidosis" and can be life-threatening if not treated properly.

Symptoms of Diabetes
Increased thirst, frequent urination, fatigue, blurred vision, slow healing wounds and injuries, patches of dark skin, either obesity or weight loss, affects weak areas/organs, etc.

Let's know the astrological significations
Glucose is ruled by Venus,
Glycogen is ruled by Jupiter,
Water signs, Moon, Venus govern liquid hormones like insulin, etc,
Water signs - Cancer, Scorpio, Pisces show inactive metabolism,
In Zodiac, 5th sign Leo and its ruler Sun mainly indicate pancreas, metabolism, Kreb's cycle.

In a natal/birth chart -
1, 5 and their lords give/improve health,
5th house and its lord rule pancreas,
6th house and its lord show diseases,
natural malefics are Saturn, Mars, Rahu, Ketu, dark Moon,
natural benefics are Jupiter, Venus, Mercury, bright Moon,
functional malefics are 6,8,12, badhaka house significators,
9th (parents) house to 1, 6 house links show diabetes by genetic causes,
2nd house to 1, 6 houses with afflictions indicate diabetes by improper lifestyle.

Diabetes disease causes several side effects
Affliction to Gemini, Mercury, 3rd H, its lord causes Lungs problem
Affliction to Virgo, Mercury, 6th H, its lord causes intestinal problems

Affliction to Venus, Virgo, Libra, Scorpio along with —
Affliction to 2nd H, its lord, shows vision defects
Affliction to 6th H, its lord causes kidney, ureter infections
Affliction to 7th H, its lord causes urinary bladder infections
Affliction to 8th H, its lord causes urethra infections
Afflictions to 9/10/11/12 houses, causes some problems to legs

Diabetes Type 1 (infection to Pancreas gland)
afflicted Sun, Leo,
afflicted 5th house, its lord
affliction from Rahu (autoimmune cheats pancreas)
Venus, Moon afflictions cause insulin hormone defects/insufficiency
affliction by natural malefics, functional malefics, badhaka significators

e.g. for Type 1 diabetes

Ascendant Scorpio, a watery sign causes lower metabolic rate,
Ascendant Scorpio is aspected by Saturn,
Ascendant lord Mars is in enemy sign and aspecting Sun (Pancreas).
Functional malefic Mercury (8th lord) afflicts Sun.
5th house is at 3° in Aries sign, aspected by Saturn, a natural malefic,
Jupiter from 25° in Libra cannot aspect 5th house, and cannot repair it.
Leo sign is aspected by Saturn,
Moon, Venus (hormones) are afflicted by Saturn and Rahu,
Moon, Ketu are related to badhaka house.
Planets mainly showing inadequate insulin for metabolism (Type 1).

Diabetes Type 2
Venus affliction is not mandatory/important
Weak/afflicted Mars shows less energy, less exercise
Ascendant and its lord afflicted in watery signs causes diabetes type 2
Jupiter's affliction causes excess storage or improper balance of fat in the body
Afflictions to Sun, Leo, 1st H, its lord - slows down metabolism or raises insulin resistance, and causes obesity (glucose converted to fat).

e.g. for Type 2 diabetes

Mars, 8th lord, natural and functional malefic, posited in 6th house, and aspecting ascendant, shows resistance to insulin, and also causes lower metabolic rate,
Mercury and Sun, both are in watery sign, this causes lower metabolic rate
Jupiter is the badhaka lord, and is in Leo sign,
Moon is at 12° in Aries, is in badhaka house (8th H begins at 25° in Aries),
Leo sign and Jupiter, both are afflicted by Mars and Saturn, 2 natural malefics,
5th lord Saturn is with Rahu in water sign. Rahu acts as Mars, signifies 6, 8;
Venus is at 4°, Mars is at 29°. So, Mars aspecting Venus too.
Ascendant, Sun, Mercury, Moon, Jupiter showing insufficient metabolic rate in body cells.
